Radar Description and Specifications The purpose of the ADSS Pulse Doppler Radar is to detect and track aircraft and other objects that are flying within specified ranges of a Wind Turbine Park. Doppler Radar measurements are used by the ADSS Central Controller to determine if aircraft are approaching the Wind Park, and to turn- on Obstruction Light Modules to warn-off incoming aircraft that are approaching too close to the Wind Park. 3.1 Electrical Specifications Description AC input voltage AC line frequency AC input power Microwave output power Microwave pulse duration Microwave pulse recurrent frequency Microwave average power Microwave frequency 3.2 Control Signal and Electrical Connections Specifications 100-240 VAC, single phase, neutral with ground 50/60 Hz nominal 550VA/500W (maximum) 12 kW (peak) 500 nanoseconds 2000 pulses per second 12 W 9.4 GHz nominal (X-Band) Description Ethernet control cable AC input power Specifications CAT/6 cable and connector, supplied by Laufer Wind 3 conductor, 16 GA SO cable and 9 pin Amphenol, supplied by Laufer Wind Laufer Wind -10 Commerce Park North Suite 12, Bedford, NH, USA 03110 -Sales and Service: (212)792-3912 5 3.3 Mechanical Specifications Description Size Weight Antenna Mounting Cooling Radome Warning labels:

Operating Instructions The instructions below describe how to connect AC power and communications to the Pulse Doppler Radar, and how to turn on and off, and control Radar operation through a Central Controller computer and software 5.1 Power and Ethernet Connections The Pulse Doppler Radar is operated and controlled by a Central Controller computer through its graphical user interface (GUI). A CAT/6 (shielded) Ethernet communication cable connects the Radar to the Central Controller computer (typically a laptop).The Figure 1 block diagram shows how the Pulse Doppler Radar and Central Controller computer can be connected, either (a) directly via a CAT/6 (shielded) Ethernet communication cable, or (b) remotely via a wireless Ethernet bridge. The Radar is connected to a single-phase (line-neutral-ground)100-240V AC power source through connector P1.

(a) Central Controller can communicate directly with the Radar through a CAT/6 Ethernet, or (b) remotely using a wireless Ethernet bridge. Figure 2 shows a drawing of the Pulse Doppler Radar housing and antenna, and radome assembly. The Radar housing and its antenna is designed to mount on a Radome/disk assembly. Figure 3 shows the input AC power cord and CAT/6 Ethernet cable connections at the bottom of the radar housing. Once AC power and Ethernet are connected, the Radar can be controlled by the Central Controller GUI.

Photograph showing how AC power and Ethernet cables are connected to the Pulse Doppler Radar. 5.2 Radar Operation These instructions cover the steps needed to operate the Pulse Doppler Radar system with a Central Controller computer. These are general user oriented instructions, and it is assumed that the system has been correctly configured for network communications. System Requirements 1. A single Central Radar Controller computer 2. One or more Pulse Doppler Radars 5.2.1 Radar Control GUI Operation Procedure The discussion below provides a step-by-step procedure for launching the Central Controller software for controlling the Radar. 1. Power up and log into the Central Radar Controller computer. a. User name is radar. b. Password is radar. 2. For hard-wired network interface connections (similar to Figure 1a):
a. If a single Radar is used, an Ethernet communication link can be connected directly to the Central Radar Controller network interface. b. If multiple Radars are used, individual Radars will be configured with unique IP addresses. The Ethernet cables to the Radars should be connected to a network switch, along with the Central Controller. 3. For wire-less network interfaces (similar to Figure 1b):
Laufer Wind -10 Commerce Park North Suite 12, Bedford, NH, USA 03110 -Sales and Service: (212)792-3912 8 a. The Central Controller can control multiple Radars remotely through a wireless Ethernet bridge. The network configuration will support multiple Radar IP addresses through the wireless Ethernet, and Central Controller will be able to communicate with individual Radars by select their respective IP addresses. 4. Start the Radar Control GUI. a. On the Central Radar Controller desktop screen shown in Figure 4, double click the icon labeled RadarControlGUI. Figure 4. Central Controller desktop screen shot. b. The program will initially display a new Radar Control GUI screen similar to Figure 5, with status as Not Connected until a Radar Processor connects. Figure 5. Screen shot showing the Radar Control GUI before it makes communications connection with a Radar. Laufer Wind -10 Commerce Park North Suite 12, Bedford, NH, USA 03110 -Sales and Service: (212)792-3912 9 5. When the Radar Control GUI has connected to the Radar Processor, the GUI should resemble that shown in Figure 6. Note that the Radar Status values in the right-hand column are updated periodically. IMPORTANT: If for any reason, it is necessary to quickly shut down the radar, clicking the big Red stop button will shut it down, as long as the communication status is connected. Otherwise, remove AC power to the radar if necessary. Figure 6. Radar Control GUI when connected to a Pulse Doppler Radar. 6. Once the Radar Control GUI has connected, select the Radar to use by choosing its IP address in the Select Radar IP Address drop-down box. a. If only one Radar Processor is connected to the Central Controller, it will be selected by default. 7. Now select a Magnetron (either A or B) for the microwave source, by choosing from the Select Magnetron drop box. a. The selected magnetron should match the Magnetron Select field in the status column (Figure 7). Laufer Wind -10 Commerce Park North Suite 12, Bedford, NH, USA 03110 -Sales and Service: (212)792-3912 10 Figure 7. Radar Control GUI showing Magnetron Select feature. 8. Turn on the Magnetron by clicking on the Turn on Magnetron button. The button command will change to Turn off Magnetron (Figure 8). The colored indicator beside the button will turn yellow and a timer will start counting while the magnetron heater warms up (90 seconds heating time). Figure 8. Radar Control GUI showing Magnetron Turn-on feature. 9. The Antenna can be made to rotate (or turned off) at any time by selecting the Start Rotation button. 10. When the heating time is complete, the button, Turn High Voltage On will become enabled
(Figure 9). Laufer Wind -10 Commerce Park North Suite 12, Bedford, NH, USA 03110 -Sales and Service: (212)792-3912 11 a. WARNING!!!: To prevent radiation exposure, be sure that a dummy load is on the RADAR for testing. If testing with an antenna, be sure that all personnel are in a safe area before activating the high voltage. The minimum safe distance from the antenna while it is radiating is 10 meters. Figure 9. Radar Control GUI showing High Voltage ready feature. 11. Turn on Magnetron High Voltage. Click the Turn High Voltage On button. This will display a prominent icon that states that the Radar is radiating (Figure 10). Figure 10. Radar Control GUI showing High Voltage ready feature. Laufer Wind -10 Commerce Park North Suite 12, Bedford, NH, USA 03110 -Sales and Service: (212)792-3912 12 12. The Radar will stop radiating when the High Voltage Off button is selected. Selecting the large red Stop button will deactivate the radar. This will put the system in a state described in Step 6, and the magnetron will have to go through another heating cycle before the radar can produce microwave radiation. 13. Optional Signal Viewer Application. Once the Radar Processor application has launched
(Step 4 above) , it is possible to view the microwave pulse waveforms from the Radar. This is done by double clicking the Start Radar icon on the Central Controller desktop screen. a. After double clicking the StartRadar icon, the SignalViewer should appear after a few seconds. The signal graph will initially be a flat line. Later, when the magnetron high voltage is turned on, the signal should appear similar to above (see Figure 11). b. Once the RADAR high voltage has turned on and the device is radiating, the Signal Viewer should show a graph of the radar signal pulse. Figure 11. Screen shot showing the Signal Viewer GUI showing Radar microwave pulse waveforms.
