Level Setting Radar Target Simulator

STR-243-42-L1 is a radar doppler simulator that operates from 18 to 26.5 GHz with a WR-42 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 a Doppler signal. Target characteristics can be adjusted by changing the I and Q channel frequency and phase. Siglent’s SDG1032X Waveform Generator or equivalent is recommended. The routing attenuation is adjusted by the level setting attenuator which can be calibrated to simulate the radar cross section (RCS).
