Summary: | A method of motion compensation for a Doppler radar system includes receiving, for each transmitted pulse of a set of transmitted pulses, a respective set of echo signals returned from a plurality of distance ranges, performing Doppler Fourier transforms on the sets of echo signals for the set of transmitted pulses to generate outputs that include detected signals in a plurality of velocity bins, and applying a respective pre-determined compensation phase vector to the detected signals in each velocity bin of the plurality of velocity bins. The respective pre-determined compensation phase vector applied to the detected signals in each velocity bin includes at least one of a first component proportional to a velocity of the velocity bin or a second component for compensating a phase compensation error associated with Doppler velocity aliasing. |
