This adjustment is made by changing the center frequency of the receiver's automatic frequency control circuit (AFC). Response speed of the A FC is 0.5 seconds. In other words, for each detent of the rotary knob, the center frequency changes after 0.5 seconds. It takes approximately 2.5 seconds for the antenna to make one turn (24 RPM = 0.4 RPS). This means that you can see a new target every 2.5 seconds. When tuning, turn the knob slowly to obtain the best image. The A FC is calibrated by this adjustment. Adjustment in MANUAL mode:
This adjustment is made by changing the center frequency of tuning range in the manual tuning circuit. Adjusting the manual tuning compensates for frequency deviation of the magnetron relative to temperature and time. It's necessary to do this adjustment when the radar is first installed and whenever the magnetron is replaced. Observe a close range and stable target echo, then turn the knob slowly to obtain the best image. After this adjustment, the manual adjustment indication on screen becomes 50 and this is the new tuning range center. Manual tuning must be selected in the echo menu for making manual adjustment of tuning.

CHAPTER 2. USING RADAR FOR THE FIRST TIME This chapter covers basic information and technical terms about radar for those who are using one for the first time. 2.1 What is radar?
RAdio Detecting And Ranging The word "radar" is an acronym for "RAdio Detecting And Ranging." In very simple terms, this is how it works. A radio transmitter sends a quick microwave pulse, and then a receiver listens for that signal's echo when it is bounced back from something in its path. The returning signal i s processed by a computer to determine its relative distance, position and bearing. This information is graphically displayed on a screen for you to see. Other boats or ships, navigational markers, landmasses and such are referred to as targets. By knowing how long it takes for a signal to return, the distance to a target can be determined. As the radar antenna scans through a 360-degree rotation, it can show where the target is relative to your position. By repeated scans, you can see which direction another vessel is moving. Buoy Other ship Radar wave Radar display Your ship Antenna Fig.2-1 What is radar?
Antenna How radar will perform is largely determined by its antenna or scanner. Increasing the size of the antenna improves long-range performance and target discrimination, or the ability to distinguish two separate targets at a distance. The critical factors are the antenna's beam width and side lobe level. Typically, a radar antenna will radiate a tightly focused beam from the front of the array. The longer the antenna array is, the narrower the beam width will be. Additionally, it will also emit smaller amounts of energy to each side. The lower the side lobe level, the less the effect of a false echo. The RA51 radars are equipped with a closed dome scanner, the RA52/53/54/55 has a larger, open array. Side lobe The beam in which the strongest radio signa l is radiated from the antenna is called the main lobe. Those beams that are radiated in other directions are referred to as the side lobes. The side lobe level refers to the difference in level (signal strength) between the largest side lobe and the main lobe. Side lobe level Beam width Main beam Side lobe Antenna 2 RA51/52/53/54/55 INSTRUCTION MANUAL 05 Fig.2-2 Antenna pattern Radar sight distance (NM) = 2.22 ( antenna height (m) + target height (m)) 2.2 Characteristics of Radar Wave Radio waves travel out from the antenna while bending slightly along the earth's surface. The amount they bend depends on atmospheric conditions. The sight distance of a radar generally is about 6% longer than the optical sight distance and is calculated using this equation:
Radar Radio Wave Line of sight Earth h2 h1 Fig.2-3 Radar wave Targets difficult to display on screen The intensity of the reflected radio signal from a target depends on the distance, height, and size of the target, as well as its material and shape, along with the radars transmitter power output and antenna size. Targets made of fiberglass, wood, or other low -reflectance materials or those that have a small incident angle are difficult to display on a screen. Sandy beaches, and sandy or muddy shallows can be difficult to catch. Because there's not much to reflect a signal back to you, a coastline can actually be closer to your boat than it appears on the screen. Actual(invisible) coastline Apparent coastline Invisible Visible 3 1 HU Fig.2-4 Targets difficult to display on screen Shadow zones of radar Radar waves propagate in a straight line. A high outcropping of land or a large ship will create a shadow zone behind it and prevent you from seeing targets on the other side. More importantly, if a mast or some part of the boat's superstructure is in the path of the antenna's sweep, this will also create a shadow zone. No targets will be recognized behind it and it could create a dangerous situation. False echoes Sometimes radar will display targets on screen that do not exist in the real world. You should be aware of how and why this happens. A. Ghost echoes Sometimes one large object very near your boat will appear as two different targets onscreen. One is the actual radar echo. The other is a ghost echo generated by a re
-reflection of the original signal. It comes back to your own boat, bounces back to the target, and then is picked up by the RA51/52/53/54/55 INSTRUCTION MANUAL 05 3 Target antenna on the second bounce. The actual echo appears at the correct distance and bearing on the screen. The ghost echo appears somewhere behind your boat. This type of false echo is also gen-
erated by re-reflection of waves from bridges, quay walls or building along shore. Direct reflection path Secondary reflection path Direction of ghost echo Ghost echo Real echo Mast etc. 3 1 HU Fig.2-5 False echoes of radar (Ghost echoes) B. Multiple echoes If there is a large vertical reflecting surface near your boat, as in the case when you pass alongside a large ship, radar signals are repeatedly bounced back and forth between your boat and the other object. Two to four images appear on the screen at equal intervals in the same bearing. This is called a multiple echo. The image appearing closest to you is the real echo. Multiple echoes will disappear as you move away from the reflecting object or its bearing changes. Real echo Multiple echoes 3 1 HU Fig.2-6 False echoes of radar (Multiple echoes) C. False echoes caused by side lobe An antenna's side lobe emissions are low power, and will not register distant targets. However, if there is a strong reflecting target near your boat, it sometimes may appear as a circular-arc false echo on the screen.
CAUTION When near large targets or land, your boat's mast may sometimes appear as a circular-arc shaped false echo. 4 RA51/52/53/54/55 INSTRUCTION MANUAL 05 Main beam Side lobes 3 1 HU False sidelobe echoes Real echo Antenna Fig.2-7 False echoes of radar (Caused by side lobe) D. Distant false echoes caused by duct phenomenon The duct phenomenon sometimes occurs when meteorological conditions create a temperature inversion between layers of air. When this happens, radar waves propagate erratically and can reach a location considerably farther away from your boat than the radar's maximum distance range. What appears onscreen is a false echo that looks to be nearer than the actual target. Since the true echo from the distant target is outside the measurement capabilities of the radar, its ap-
parent distance will change when you change ranges, and you can conclude that it's a false echo. Radar interference If another boat's radar is operating on the same frequency as yours, it can create interference on your display. The interference usually appears as spiral or radial patterns. The RA51/52/53/54/55 radar has two levels of interference rejection control to eliminate interference. Turn it on to re-
duce or eliminate the interference. Radar inrterference 3 1 HU Fig.2-8 Radar interference RA51/52/53/54/55 INSTRUCTION MANUAL 05 5 2.3 Terms Specific to Radar HM (Heading Marker) This is a line-shaped marker used to indicate the forward direction of your boat. North Mark The marker to indicate the direction North is a short line a p-
proximately 1/6 of the screen size. It only appears when the radar is connected to a suitable heading source provided through NMEA, 10/12 bit serial or sin/cos. North Mark 0.75 0.25 HU HM(Heading Marker) Fig.2-9 Heading Marker and North Mark Ship's Heading Display modes five (+HS) The RA51/52/53/54/55 has four display modes. Each refers to the top of the screen as it relates to the direction of your boat's travel. Ship's locus

It gives you the position of other targets around you relative to your boat. North Up (NU) In this mode, North is at the top of th e screen. This allows you to compare your position with a chart as you navigate. Heading data input is required for this mode to function. Course Up (CU) This is similar to North up except that your boat's destination is at the top of the screen. A straight line from the bottom to top of the screen is your course bearing. 6 RA51/52/53/54/55 INSTRUCTION MANUAL 05 True Motion (TM) In this mode, the boat icon is displayed as if it is moving on a marine chart while targets such as islands and seashores are fixed in position. When the icon reaches a certain position on the screen
(approx. 2/3 of screen size), it is placed back on the opposite side on the screen. North is at the top of the screen. External heading and speed data are needed for this mode. VRM (Variable Range Marker) This adjustable circular-shaped marker can be used to determine the distance of a target from your boat. When measuring be certain to move the VRM to a point close to the center of the echo image on the screen. 0.75 0.25 HU Echo VRM VRM Fig.2-11 VRM EBL (Electronic Bearing Line) This straight-line marker can be rotated in any direction centered on your boat's position.

Equal intervals Echo 0.75 0.25 HU EBL EBL Fig.2-12 EBL RA51/52/53/54/55 INSTRUCTION MANUAL 05 7 STC OFF STC (Sensitivity Time Control) Since echo signals received by the radar are stronger when they are coming from a short distance, it's difficult to compare signal strength between each reflected signal. To overcome this, signal strength is adjusted in such a way that the received signal levels coming from a short distance are lowered. This is helpful when there are large reflected waves from sea surfaces during rough weather. Echo is suppressed around center STC ON 0.75 0.25 HU 0.75 0.25 HU Fig.2-13 STC FTC OFF FTC (Fast Time Constant) When it rains or snows, fine noise may appear over the entire screen, making it difficult to identify echoes.

(f) 3.3 Where to Install the Scanner _____________________________ 3.3.1 Scanner unit Radar's target detection capacity varies greatly depending on the position of the scanner. An ideal position is a location high above the ship's keel line where there is no obstacle all around the scanner. In an actual ship, such an ideal location is limited by various factors. To comply with FCC RF exposure requirements, the radar antenna for this scanner must be installed to provide a separation distance of 1.3 m or more from all persons.
(a) Install the scanner as high as possible. Consider the structural support of the location. Will it hold the weight of the scanner?
How difficult will it be to get to the scanner for maintenance?
Install the scanner away from masts. If the scanner is installed at the same height as a mast, radar waves may be bl ocked, creating shadow zones or generating false echoes. Install the scanner forward of obstacles. If you can't avoid an obstacle, place the scanner on the bow side of it. When installing the scanner on a mast, position it in front of the mast. (If obstacles cannot be avoided for structural reasons, refer to "Shifting away from obstacles" in Section 3.3.3.)
(b)
(c)
(d) Do not install the scanner near hot or heat-generating items. Do not install the scanner where it may be subjected to smoke or hot air from exhausts or heat from lights. Install the scanner away from other antennas. Keep it as far as possible from the antennas of other electronic equipment. Radar scanners will cause interference with radio transceivers. Keep them as far apart as possible
! CAUTION Keep the cable length as short as possible. Keep the distance from the scanner to the display unit within the standard cable length of 10 m (or 15m). If you need a longer cable, limit the length to a maximum of 100 m. 3.3.2 Display unit The display unit can be installed in a helm console, bulkhead, or electronics box. Consider these suggestions:
(a) A place where you can see the boat's bow when looking straight up from the radar screen.
(b) A place where there is no direct sunlight to avoid display temperature buildup.
(c) A place where there is good ventilation and minimum vibration.
(d) A place where the display unit is more than the minimum safe distance from a magnetic compass as listed in Tab.3-5 below. Tab.3-5 Minimum Safe Distance from Magnetic Compass Standard compass Steering compass Scanner unit Display unit 2.0m 2.0m 1.4m 1.4m RA51/52/53/54/55 INSTRUCTION MANUAL 05 11 3.3.3 Shifting away from obstacles
Shifting from keel line By shifting the scanner position from the keel line to the starboard side of the boat, it is possible to move shadow zones to the port side. This makes it possible to keep a clear view to the bow. The distance to be shifted can calculated using the following equation:
Ls=0.4R+D/2 [m]
Ls=0.025R+D/2 [m]
(when R<15m)
(when R>=15m) where Ls = distance to be shifted from keel line D = diameter of obstacle on keel line R = distance from scanner to obstacle Scanner Unit Obstacle Ls D Keel line R Fig.3-1 Shifting from keel line
Obtaining sufficient dip angle Raise the scanner position so that there is a sufficient dip angle q available between the line of sight from the scanner to the obstacle and the horizontal line. By raising the dip angle above 5 , it is possible to prevent mid- and long-distance shadow zones. The radar cannot detect objects below the line of sight. q Horizontal line Line of sight Fig.3-2 Obtaining sufficient dip angle RA51/52/53/54/55 INSTRUCTION MANUAL 05 12 3.4 Installing Scanner Unit _________________________________ Use a mounting base such as the ones shown in Fig. 3.3, or you can install the scanner directly to a roof or other flat surface. Be certain you keep the water drain tube clear. It's located at the bottom of the scanner unit. Note : If the mounting bracket or surface has a curvature of more than 2mm, use spacers with the mounting bolts to prevent stress on the scanner housing. Do not use an edge that might trap water. Fig.3-3 Mount base Use the template provided with this manual to drill five holes for mounting the scanner. At-
tach the four bolts and feed the drain tube through the fifth hole. The bolts included with your unit will suffice for mount base thickness of 9 to 14 mm (0.35 to 0.55 in.). If the mount base is thicker or thinner, refer to Tab.3-6. Use a silicone sealant to prevent the bolts from working loose. The housing may be damaged if you use a thread-locking compound. 12f 5

power supply cable.
- Do not tie the cables for the radar together with cables of other equipment, especially the
- If you need to pass the cable through a wire chase or conduit, tape the scanner side con-
nector to the wire so it doesn't pull off or get hung up.
- Secure cables in place at intervals of about 40 cm (16"). 3.7.1 Interconnecting cable (RA51 Radome scanner) (See Fig.3-8-2) 1) Be sure that the power is off. Connect the cable to the plug labeled "SCANNER" on the rear panel of the display unit. Be sure to secure the rubber boot around the cable connector rim. 2) Remove the upper part of the radome from the scanner unit. Lift it vertically to avoid bumping it against the antenna. (There are four fixing screws.) 3) Remove the tape securing the antenna. 4) Remove the shield cover located on the backside. (There are four screws.) 5) Remove the cable clamping plate and rubber ring, pass the cable through the opening, re-
place the rubber ring, and clamp the cable to the scanner unit with screws on the fixing plate. Attach the 7-pin connector to X11 and 9-pin connector to X12 of the printed circuit board. 6) Replace the aluminum cover. Lay the cable shield into the channel machined into the aluminum housing.

tro-magnetic interference (EMI). However, when the unit is placed close to a radio trans-
ceiver and either piece of equipment is not properly grounded, the radar will cause inter-
ference. Here are some hints on how to reduce EMI due to radar.
(1) Installation Location The display unit, scanner unit and interconnecting cable should be located as far as possible from the transceiver, antenna cable and antenna of the radio. Experiment with various posi-
tions of both to see if it improves the condition.
(2) Laying Power Supply Cables The best solution is to run separate power wires from each unit directly to the boat's electrical supply source. A connection should be made at the main breaker panel or as close to the generator or battery as possible. Connection A and B are recommended. Connection C should not be used.
