Test signal generator for coherent air-to-ground radars
Abstract
A test signal generator for on the ground testing of coherent air-to-ground radars has a rotating antenna for simulating aircraft motion when receiving return radar signals. An angular position sensor provides a signal which is proportional to the angular position of the rotating antenna. Correlation of these signals in the radar computer provides a radar test signal having realistic amplitude and Doppler histories.
