Time Domain Corporation has developed this hand-held radar system to detect the movement and range of personnel in the presence of other obstructions. The RadarVision 1000 monitors very specific range gates, reducing the potential for false alarms created by movements made outside the area of interest. Additionally, short duration pulses that transmit power over a large bandwidth provide an advantage by making the system exceedingly covert. Because of these and other features, the RadarVision 1000 provides an optimum product jor field use. testing, evaluation, and guidance for future developments. RadarVision 1000 is the first in a family of products that incorporate Time Modulation Ultra-Wideband (TM-UWB) technology. The RadarVision 1000 is a single-unit, battery-powered, man-portable device that can detect the presence of motion through structures, debris, foliage, and other nonme-

tallic boundaries. The Radar Vision 1000 scans incremental range slices within its operational field and maps that impulse response into memory. By rapidly comparing subsequent scans, variations in impulse response can be correlated to motion. The result is the capacity to detect the presence of moving entities within the mapped area. The RadarVision 1000 not only has the flexibility to capture data, but also allows development of motion mapping, radar imaging, and target discrimination. The RadarVision 1000 provides critical, real-time information with a low probability of detection (LPD). The device overlays and operates with other existing radio transmit-

ters and receivers without interference and maintains covert conditions by spreading its low power pulses over a wide bandwidth. This manual explains the operation and care of the RadarVision 1000 unit. Some helpful terminology is included to increase understanding of the technology and general operation of the RadarVision 1000. TIME DOMAIN" i FCC ID: NUF-CW RadarVision 1000 VLO8.99 PREFACE TERMINOLOGY Unless otherwise specified, the terms unit, radar, and system are used interchange-

ably in this manual to refer to the RadarVision 1000. Area of View - The beam pattern radiated by the antenna can be described as the intersection of a cone and a sphere, with a 120 field of view (120 azimuth by 100 elevation). This area can be thought of as a half-caten ice cream cone, where the portion of the ice cream left inside the cone describes the space (Fig. p. 1). The radar shield starts its coverage wide and curved and then flattens out as it moves farther away from the radar. The area of coverage is not perfectly shaped like a cone, as the sides nearest to the antenna bulge out somewhat. When specifying a range gate, the measurements that are referred to can be thought of as an arc in space with the beginning and ending measurement being drawn through the forward center of the arc

(ie., range gate of 5 feet would be measured directly from the center of the antenna outward by 5 feet). (See Range Gate, Window)

/ Range Gate Boundary

|. Radar, top view Range Gate Area Figure p. 1 Area of View Bin - A delay value required by the receiving antenna to control which range gate is being observed. ii TIME DOMAIN FCC ID: NUF-CW RadarVision 1000 V108.99 PREFACE Blanking - An algorithm that prevents alarms at more distant range gates. This is a method designed to aid user interpretation of a signal by ignoring the shadow effect and multipath. Coupling A signal that propagates directly from the transmit antenna to the receiv-

ing antenna without reflecting an object. Process Gain The gain (improvement in signal-to-noise ratio) resulting from processes after the signal is received. Many data samples are collected and averaged. By averaging the signal, the signal-to-noise-level compared to a single sample is improved, resulting in a process gain. Propagation - The way in which a radio signal travels through the air and reflects from or penetrates the materials around it. The effect of propagation on radio signals often results in a loss of signa! returning to the antenna. Propagation can also influence shadow effect. Range Gate - A selected zone being monitored at a specific range (Fig. p.2). The unit is designed to detect motion at a specified distance from the antenna and includes an area preceeding it. Objects may be nearer than they are indicated to be. For example, if motion is detected at 14 fect (as below), the radar will indicate activity in the 15 foot range gate display. Default range gates are set to 5, 10, 15 and 20 feet. Figure p. 2, Range Gates TIME DOMAIN iti FCC ID: NUF-CW RadarVision 1000 V108.99 PREFACE Shadow Effect - The radar monitors multiple range gates to determine if there are any changes within a single, specified range gate. Any observed changes indicate movement within that range. However, movement detected in close proximity to the radar will block a portion of the energy that is propagated to further ranges. This movement may cause a shadow to be cast upon the more distant ranges. The shadow effect in the more distant ranges will cither cease or follow in conjunction with the movement as it travels through the specified range (Fig. p.3). As a result, an operator of the system can easily discriminate real movement from shadow effect. With a single look angle, as in the case of this unit, a subject moving in a close range gate may cast a shadow at a more distant range gate. The radar system effectively gees not only the presence of the closer target motion, but also detects the apparent absence, as the signal is prevented from reflecting from objects that are more distant. Rear subject intially hidden by shadow of forward subject. Figure p. 3 Shadow Effect Motion detected at 10 feet. Activity at 15 feet also registers initially, but does not discriminate until second object either moves or remains stationary. iv TIME DOMAIN RadarVision 1000 V108.99 PREFACE Time Modulation - A variation of the time periods between pulses. When UWB systems transmit a uniform pulse stream, energy is concentrated at discrete harmonic frequencies within the bandwidth. By randomizing the timing of sequential pulses (as shown in Fig. p.4), a noise-like signal is produced, and coherent harmonics are Te-

duced, This variation has many benefits, including reduction of range ambiguities, improved co-location, improved covertness, and better electromagnetic compatibility. PULSE POSITION HOM, PULSE PERIOD Figure p. 4. Time Modulation Time Modulated Ultra-Wideband Radar - A low-energy, exceptionally wide band radar and coherent correlating receiver that utilize both time-modulation and ultra-

wide bandwidth to generate radar images through walls. TM-UWB technology uses very short duration, pseudo-random time encoded electromagnetic pulses (Fig. p.5). The resultant transmission is a noise-like signal that is spread over a wider frequency range than conventional systems. These low power, TM-UWB signals are very difficult to detect. Command and Figure p.5 Time Modulated Ultra-Wideband Radar TIME DOMAIN FCC 1D: NUF-CW RadarVision 1000 V108.99 PREFACE Ultra-wide Bandwidth - The Defense Advanced Research Projects Agency

(DARPA) has defined ultra-wideband as a system that has a fraction bandwidth, the ratio of the bandwidth divided by the center frequency, greater than 25%. Window - The range gate or ccll, from the closest to the farthest range, as it is scanned. vi TIME DOMAIN"

RadarVision 1000 V1L0.8.99 a S OPERATION 3 INTRODUCTION TO THE RADARVISION 1000 sysTEM The RadarVision 1000 was designed to be used as both a portable unit and as a fixed location unit. Depending upon the use of the product, operation may vary slightly. The following section will provide the user with gencral operating procedures and will help familiarize them with alternatives to standard use. Environment It is best to limit exposure of the unit to any dust, humidity, and temperature fluctuations that might make the unit susceptible to condensation. It is also important to establish an uncluttered area for testing the units performance. If the radar is pointed in a direction where movement occurs outside the test area (such as a hallway on the other side of a test wail), then the unit may indicate unwanted movement during testing. Portable Use When operating the unit portably, the following criteria should be considered:

. Use a solid surface (such as a table or wall) to support the radar. Steady the unit against a wall or other surface when supporting the unit by hand. Unwanted readings may result if operator is not completely still. Have both batteries fully charged and ready for use.

: Do not shake or jar the unit unnecessarily. Battery Before operating the unit with the battery, you must charge the battery (it may take as long as 12 hours to charge completely). Plug the battery charger into a suitable 110V outlet, and attach the socket connector on the battery to the matching charger connector. To replace the rechargeable battery with the backup battery. do the following:

. Turn the unit OFF. Detach cable from the unit to the battery. Unscrew the two locking screws and remove the battery. Insert the tab on the bottom of the new battery into the metal slot on the case.

: Swing the battery toward the case. Tighten the two locking screws. Reattach the cable to the unit. TIME DOMAIN 9 RadarVision 1000 V108.99 OPERATION Fixed-location Operation When operating the unit in a fixed or permanent location, the following criteria should be considered:

. Provide a smooth, level, and stable surface to support the unit. (Tripod available)

. Face the rear (antenna) side of the unit toward the area to be scanned. Plug in the power cables. Power Supply and Electrical Outlets Turn the power supply ON before powering up the RadarVision 1000. Standard 110V grounded electrical power outlets (with no UPS required) are sufficient to operate the power supply. RADAR OPERATION The RadarVision 1000 (used as a stand-alone unit) has a Main Interface LCD screen that displays radar activity and provides limited messaging (Figure 3.1). There are three user control functions (Tone. Mode, Attenuation), a battery life indicator, an ambient noise indicator, a tone indicator, a mode indicator, an attenuation indicator, and a heartbeat indica-

tor, Each facet of the interface will be described below. Indicators Tone Button Attenuation Button Mode Button Figure 3.1 Main Interface (Motion Display) 10 TIME DOMAIN"

RadarVision 1000 V10.8.99 OPERATION en Main Interface (Motion Display) When the RadarVision 1000 is turned on, a Boot Up screen will appear displaying company information and the message. Please wait while radar boots. The boot up should take approximately 30 seconds. (If the unit fails to boot after 40 seconds, turn the radar off and restart). The Main Interface screen will then appear. This back-lit LCD screen provides the user with a real-time motion display that shows where movement is occurring. Each of four bars represents a specific range gate (See Terminology section). The radar is preset to 5, 10, 15, and 20 foot range increments (displayed from left to right). If movement occurs within a range gate, the representative bar will show a solid fill. Wherever activity is greatest, that bar will fill the most. Other bars may show activity duc to shadow effect (See Terminology section) or due to movement in that additional area. Generally, the operator can recognize the difference between shadow effect and movement occurring within distinct range gates. If activity is duc to shadow effect, the bars will show consecutive activity in descending order (i.c., the 5 foot range gate will register a solid fill. and the 10 range gate will register a partial fill). With shadow effect, as the movement stops or passes out of the range, the other affected bars will quickly stop registering any activity. If, however, the bars register activity due to movement in two separate range gates, two non-

adjacent bars may fill, or two adjacent bars will fill fully. The parameters for each range gate can be changed via the RadarVision 1000 Controller Software (See RadarVision 1000 Controller Software Manual for details). Tone The Tone button controls the audible alarm. When Tone is activated, a combination of beeps will sound as activity is being registered. When Tone is deactivated, the alarm is silent. Press to toggle between Tone ON and Tone OFF. Mode The Mode button allows the user to change the manner the received data is displayed; either threshold ot continuous mode. The first mode (threshold), is the default and is applicable for normal operation. Threshold mode displays data registering in each range gate after an automatically controlled threshold has been applied. Motion registering in this mode is usually caused by a distinct movement. This prevents false alarms that may be caused by finer movements from such things as fans, wind, small animals. etc. TIME DOMAIN" 11 RadarVision 1000 V108.99 OPERATION SS The second mode (continuous) allows the user to monitor the raw data being continuously read by the radar. This mode is used to determine the base ambient readings and to identify very slight movements, such as breathing. Continuous mode displays the bars filled halfway. This half-way point becomes, in effect the 0 point. In this regard, the user would be able to see all movement registering in each channel. This information shows the continuous data being recieved by the radar before processing. This mode would mainly be used for testing procedures and development. Att The Ad (Attenuation) button is designed to allow the user to increase or decrease the sensitivity of the units receiver. The indicator for Aff is on the second row of the top left-hand corner of the LCD display (Figure 3.2). The default setting is 20 dB. Each time the Att button is depressed, the attenuation will increase by 5dB units to a maximum of 30dB. The attenuation then cycles back to 0 dB. By altering the attenuation setting, the sensitivity to the received signal will be affected. The lower the dB value, the lower the sensitivity. The higher the dB value, the more sensitive the unit will become (while the transmitted signal is not affected). A user may choose to raise the attenuation setting to achieve more sensitivity when, for example, the readings from the radar must be taken through particularly thick walls. Battery Life The Bar bar graph (top right-hand portion of LCD display - Figure 3.2) shows the relative amount of life left in the battery. A solid bar represents full charge; an empty bar represents no charge. While the radar is powered by the power supply, the battery life indicator will show active power to the unit with a half-filled bar at 12 Volts. The bar will register as full if the power supply reads higher than 12 Volts. Heartbeat Indicator Battery Life Indicator Tone Indicator Att (Attenuation) Indicator Ambient Noise Indicator Mode Indicator Figure 3.2. Indicators 12 TIME DOM4IN RadarVision 1000 V1.0.8.99 OPERATION ST Ambient Noise The Awa bar graph (second row of the top right-hand portion of LCD display - Figure 3.2) shows any ambient noise being picked up by the radar. This includes all jamming and interference. When there is any ambient noise being registered in this graph, the motion data displayed by the radar cannot be considered accurate. The user is encouraged to check the area for potential interference (cellular phones, etc.) and remove them if possible.

~< Mode Indicator This symbol (Figure 3.2) represents the mode that is currently in operation. When the arrow is pointing to the left, the mode is set to auto-threshold (default). When the arrow is pointing up and down, the mode is set to display continuous data being received by the radar.
