<p>A pulse radar range profile motion compensation method (10) comprises: acquiring receiver samples (12); acquiring an estimate of the range rate of a target (14); removing an additional phase acquired by the echo signals; removing a shift in range cells of the receiver samples (18); applying a pulse Doppler filter (22); identifying the peak Doppler frequency and calculating a shift from zero of the peak Doppler frequency (24); calculating a range rate correction (26); adding the range rate correction to the estimate of the range rate and repeating the removal of the additional phase (16) and the shift in range cells (18), and using the new range rate estimate to obtain motion compensated receiver samples (28); and generating an output signal indicative of the motion compensated receiver samples for generating a range profile (30).</p> |
