Level Setting Radar Target Simulator

STR-773-12-L1 is a radar doppler simulator that operates at 76.5 GHz with a bandwidth of ±250 MHz and a WR-12 waveguide input/output. The simulator utilizes a single-sideband-modulator to modulate the incoming signal transmitted by the radar under test and sends back either a higher or lower band signal through a diplexer. The frequency-shifted signal is transmitted back to the radar under test as the Doppler signal. Target characteristics can be adjusted by changing the I and Q channel frequency and phase. The routing attenuation is adjusted by the level setting attenuator which can be calibrated to simulate the radar cross section (RCS).
