For detailed explanation, refer to each item in this manual. 1 . 1 . Press the [ ] to turn BRILL on the power. 2. When [ST'BY] appears, press the [STBY/TX] key to start the transmission. 1.3 Power On/Off 1.5 Transmission 5 . Rotate the [STC] knob to adjust the sea surface reflection suppression effect. The suppression fect becomes strong when rotating clockwise the knob and becomes weak when rotating counterclockwise the knob. This function reduces the gain at a near distance. If you turn clockwise the knob
. Adjust properly to meet the weather too much, desired objects may disappear. condition. Example of STC adjustment :
: The suppression is too weak. The reflection from sea surface is displayed.
: Optimum suppression. The desired objects are displayed.
: The suppression is too strong. Some objects are not displayed. 1.8 STC adjustment 1-1 0093120007-01 MDC-2000A Series Chapter 1 Basic Operation 3 . Change the observation range with the [- RANGE +] key. When pressing the [+] key, the observation range expands. When pressing the [-] key, the enlarged surrounding around own ship can be observed. To make it easier to observe the range you desire, change the range. Example of display :
Long range : Far distance Middle range : Middle distance Short range : Near distance Objects at far distance can be covered. Objects near own ship can be easily confirmed. 1.6 Switch-over of range 4 . Adjust the gain by rotating the [GAIN] knob. The gain becomes high when rotating clockwise the knob and becomes low when rotating counterclockwise the knob.
When the observation range is narrow or targets are crowded, reduce the gain so that targets can be easily seen. When the observation range is wide, if the gain is increased, it is effective. But, due to noise increase, small targets become hard to be seen.
Example of gain adjustment:
: Too high gain

MDC-2000A Series Chapter 5 Installation Chapter 5 Equipment 5.1 Antenna Installation Determining the location of the installation The search capability of the radar varies largely, depending on the position of the antenna installation. The ideal installation position is the high place over the keel line where no obstacle surrounds. Actually, though there are many limitations in a ship, determine the installation position, considering the following items. 1. The antenna block should be over the line drawn between the bow and the stern, and should be installed to a position where no obstacle to block the radiation path of the radar beam is present. 2. To avoid the electromagnetic wave interference with human bodies, install the antenna block higher than the living space by 0.6m. However, if installed at the higher position, objects at the near distance cannot be searched. Thus, when approaching to a pier, if the radar is used, you must pay attention. The higher the position of the antenna is, the stronger the reflection from the sea surface becomes. 3. Keep the surface of the platform, where the antenna is installed, horizontal as possible to be parallel with the sea surface. Install the antenna lock in front of the large structure and exhaust chimney to avoid the blind sector (inability angle of image search) on the screen and to prevent the opening of the antenna from being dirtied by the engine exhaust. 4. 5. Keep enough space for maintenance. 6. To prevent a blind or ghost from occurring in the heading, place the antenna towards the bow rather than obstacles, keep it away from obstacles. And when installing the antenna on the mast, place it in front of the mast. (If obstacles cannot be avoided due to limitation of structure, refer to
[How to shift the antenna from an obstacle] described later. 7. Keep away the antenna from other equipments antenna. Keep a distance from antennas of a direction finder and a VHF transmitter-receiver as far as possible. 8. Keep a distance for safety from the magnetic compass. Type of Scanner RB805 RB806 Safety Distance from Magnetic Compass Standard Compass Steering Compass 2.0m 2.0m 1.4m 1.4m WARNING Install the antenna, keeping it away from wireless equipment not to be interfered. 0093120007-01 5-1 Chapter 5 Installation MDC-2000A Series How to shift the antenna from an obstacle 1. How to shift the antenna from the keel line By shifting the antenna from keel line to the starboard, the blind moves to the port and the visibility in the heading can be secured. According to a distance to an obstacle, the distance to be shifted can be derived from the formula below. Distance to be shifted from the keel line Diameter of an obstacle over the keel line Distance to an obstacle Antenna Obstacle Ls D R How to shift the antenna from the keel line Keel line 2. How to keep an angle of depression To keep enough angle of depression that is an angle between the horizontal and the observers line of sight (In this case, it is not the observer but an antenna), elevate the antenna height. By making more than 5, the blind at the middle and long distances can be avoided. An object below the line of sight cannot be detected. Horizon Line of sight How to keep an angle of depression 5-2 0093120007-01 MDC-2000A Series Chapter 5 Installation Installation of Antenna After determining the location of the installation, install the antenna. When installing, if the bracket shown below is available, the installation is easier. If not available, install the antenna directly on the roof, paying attention to the air tube for drain at the bottom of the antenna. Note: If the radar mast or installation bracket is warped more than 2mm, make it flat or adjust by inserting spacers. Do not use the edge as it causes a sump. Bracket Installation of Radome Antenna Referring to the illustration below, make five (5) holes on the cradle and fix the bracket and the antenna together with hexagon bolts. If the thickness of the bracket is 9 to 14mm, it can be installed with the supplied bolts. If not within this range, prepare bolts shown on the table in the next page. To prevent the looseness from occurring, fortify with the commercially available loose-preventive silicon sealing. However, for preventing the looseness of the radome antenna, do not use the putty. The putty may deteriorate chemically the plastic material of the radome. 65

The radar system is a navigation device that transmits a very high frequency radio wave referred as microwave from antenna. The radar then receives the radio wave reflected by target(s) (e.g. other ship, buoy, island, etc) via the same antenna and converts the received radio wave to electronic signals and sends these signals to the Display unit. The radar makes it possible to find objects (targets), such as other ships, rocks or coastline, not seen by eyesight or in fog and allows ships to avoid these potential hazards. As the antenna transmits while rotating, it is possible to see the current surrounding situation around your ship at a glance. The microwave radiated from the radar is referred as pulse wave and transmitting and receiving of these waves alternate. Up to thousands of pulse waves are transmitted and received during one 360 degree rotation. The typical radar antenna is a parabolic type or slotted array and its performance is essential for good radar performance. Some of factors affecting the quality of the target returns are the antenna beam width and the side lobe level. The narrow beam width provides a high resolution for angular orientation to distinguish objects and the low side lobe level reduces a false image effect. Other ship Radar display Buoy Ot he r ship Ra dar wave Own ship Antenna
(during rotating) Side lobe The main lobe means the strongest radiated beam sent from the specific antenna, and the other weaker beams, are referred as side lobes. A side lobe level is a difference between the largest side lobe level and main lobe level. Figure 7-1 What is Radar?
Side lobe level Main lobe Beam width Side lobe Antenna Figure 7-2 Antenna pattern Beam width The antenna beam width is defined as the angle where the radiation power density is within a half of the maximum power supply in the main lobe (also, referred as half value width). 0093120007-01 7-1 Chapter 7 Principle of radar system MDC-2000A Series 7.2 Characteristics of radar radio wave The radio wave propagates slightly along the ground (primarily line of sight). This characteristic varies depending on the density of atmosphere but generally calculated according to the formula as shown below, considering that the distance with radar sight D is about 6% longer than the distance with optical sight. D(NM)=2.22 X ( h1 + h2 ) h1 : Antenna height (m) h2 : Target height (m) Sight line Radar radio wave h 1 Earth Figure 7-3 Characteristics of radar radio wave h2 Target with less reflection The strength of the reflected waves from a target varies depending on not only the distance from the target, its height or size, but also (radar absorbing) material and shapes. A target with a low degree of reflection or low incident angle, such as FRP and wooden is not reflected well. Therefore, care should be taken that a FRP ship, a wooden ship or an object such as sand, a sandbar and muddy cay poor radar targets. Since the distance from the coastline, etc. to your ship on a radar image to be seen as longer than that from the actual coastline, more caution should be used navigating around such objects. 3 1 HU Seen Not seen Actual (not seen coastline Radar shadow Since the radar radio wave propagates straightly, your ships chimney stack and mast close to the antenna, a large ship or mountain can create blind spots for which the radar wave cannot penetrate. In such cases, they may completely or partially hide targets and cast a long shadow. Since the shadow your ships chimney stack or mast is known at the time of installation, proper selection of the antenna location is required to reduce the shadow effect. Since targets less likely to be in this shadow area than in open sea, an extra attention should be taken in shadow areas. False image An image that does not actually exist (false image) at sea may appear on the display. The phenomenon that causes false echoes are categorized and be described as follows:
Figure 7-4 Example of targets hard to be reflected 7-2 0093120007-01 MDC-2000A Series Chapter 7 Principle of radar system Virtual image The image of a large physical object in a close proximity may appear in two different orientations. One is a real image and the other is a false image caused by wave reflected on the chimney stack or the mast, etc. On the display, one image appears with a right distance and bearing, and another one appears in the direction of chimney stack, mast, etc. These images may also be generated by being reflected multiple times from the bridges and quays too. Passage of direct reflection Real image 3 1 HU Passage of secondary reflection Mast, etc Direction of virtual image Figure 7-5 False image by virtual image Virtual image Duplicate target images When there is a big reflective surface nearby and perpendicular at a close distance (i.e. when your ship is passed by a big ship, etc.) radio wave bounces repeatedly between your ship and the other ship. Therefore, 2 to 4 images may appear at equal range in the direction of this target. The false image generated by this multi-path reflection is referred as double targets. In this case, the closest target is the real one. Even if the double targets appear, if the distance and bearing between own ship and the reflective target changes, the duplicate targets will disappear. Therefore, this false image can be easily distinguished. 3 1 HU Real image Own ship Large vessel Double image 0093120007-01 7-3 Chapter 7 Principle of radar system MDC-2000A Series False image by sidelobe The microwave beam radiated from the antenna has a side lobe in different direction than that of the main beam. Since this side lobe is lower than that of main beam, the effect is negligible for targets at a long range, but a close, strong reflecting target may cause false image in a circular arc shape. Main lobe Side lobe If a large target such as land exists near your ship, a circular arc shaped image may appear. 3 1 HU False image by sidelobe Antenna Real image Figure 7-7 False image by sidelobe False image of a distant target caused by duct Depending on a weather conditions, a duct occurs by the temperature inversion, etc. In this case, the unusual propagation of the radio wave may reach distant targets out of radar range. A target at more than the maximum range may appear as an image, and may be displayed as a false image closer than an actual distance. This phenomenon is a result of the long range echo delay time exceeds the transmission period, and is displayed as the echo in the next cycle. When changing the range of a distance, if the distance of the target changes, it can be judged as a false image. 7.3 Radar interference When the radar with the same frequency band is used nearby, interference noise appears on a display. Although appearance of interference is not constant, the shape is almost always swirling or radial. This device features an interference rejection facility to reduce interference. 7-4 0093120007-01
