SIMULATOR FOR MONOPULSE RADAR HAVING COHERENT DOPPLER FEATURES

摘要

A device for simulating radar echo "video" signals as would be produced by a monopulse radar system having coherent pulse Doppler features. A low frequency signal is processed by multiple sampling, first by a pulse at the radar PRF which varies in time phase at the azimuth scan rate. Application of the resulting samples to a filter having an impulse response resembling the antenna beam pattern is followed by a controllable sampling to inject the dimensions of simulated echo angle and range. The result is realistic target signals which can be applied directly to a radar indicator for training of operators in the operation of monopulse tracking Doppler radar equipment.
