Direct Reading Radar Target Simulator

STR-243-42-D1 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 are adjusted by changing the I and Q channel frequency and phase. The routing attenuation is adjusted by the direct reading attenuator.
