GMTI motion compensation
First Claim
1. A method of compensating for defocusing of range-Doppler map in a GMTI radar video signal caused by movement of radar during a coherent processing interval over which a set of radar pulses are processed, comprising varying waveform or sampling parameters of each pulse on a pulse-to-pulse basis to compensate for distortions caused by variations in viewing angles from the radar to the target.

Abstract
Movement of a GMTI radar during a coherent processing interval over which a set of radar pulses are processed may cause defocusing of a range-Doppler map in the video signal. This problem may be compensated by varying waveform or sampling parameters of each pulse to compensate for distortions caused by variations in viewing angles from the radar to the target.
