Abstract
Various technologies pertaining to motion compensation for radar systems using FM waveforms are described herein. A waveform generator outputs a parametrized, pulsed FM waveform to a radar antenna, whereupon the radar antenna emits pulsed electromagnetic (EM) radiation into a target area based upon the parametrized FM waveform. The parametrized FM waveform compensates for motion of a radar platform that includes the antenna. The parametrized FM waveform compensates for inter-pulse Doppler effects by introducing a time delay to a reference FM waveform, and compensates for intra-pulse Doppler effects by time dilating, or frequency-scaling, pulses of the reference waveform. The parametrized FM waveform can be generated by modifying the reference waveform based on first and second parameters, where the parameters are based upon motion of the radar platform and changes in echo return delay times from one pulse to another.
