| 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. |
