2. REMOTE TEST TARGET
2.1. Theory
For Remote Test Target (RTT) usage the RTG1002 is deployed in the field, typically connected to two small
horns or Log Periodic Antennas positioned on a pole or tripods with a limited height. This way, the radar
antenna system becomes part of the test. The area where a target can be simulated is limited to the azimuth
of choice and a range further than the chosen position. The simulated target can be moving radial or be
fixed.
The fixed target can appear as point clutter (no Doppler) or can have a simulated Doppler frequency.
2.2. Software
Warning: Before you start making connections, estimate/calculate the distance of the set-
up. Whenever you are close to the radar (<200m) add some attenuation to Tx and Rx plug
before you make the setup. The maximum power level at the input should not exceed
+10dBm and the power level at the output should not exceed +20dBm.
1. Load the RTG1002 PSR Target Generation software from the Scenario Generation button in
the PSR Generation section of the RASS-S toolbox.
2. Make sure the network cable is connected between J12 and J13 or J14. Click the little white arrow in
the top left corner to run the vi.
