摘要：
A digital processing algorithm for fine resolution imaging of synthetic aperture radar (SAR) moving targets is described. The targets may have any transí aliona and rotational motion components relative to the data collection platform. The algorithm requires the presence of up to three prominent points in the image of the target; the signals from these points provide estimates of the unknown target motion parameters. Phase compensation and data formatting based on these estimates eliminate motion-induced phase errors. This algorithm has been implemented on a VAX computer and used to process both simulated and real SAR data of moving targets. Results are presented with the simulated data. © 1990 IEEE
