Abstract

Synthetic aperture radar (SAR) is used for imaging of terrain and stationary objects. For stationary targets, Doppler drifts are determined only by their geometric locations. However, for moving targets, the Doppler drifts are determined not only by their locations but also by their velocities. Therefore, the SAR images of moving targets become smeared due to interactions between their geometric locations and velocities; the cross-range of moving targets does not reflect their true geometric locations. In this paper, we analyze the effects of target motion on SAR images, review methods for SAR imaging of moving targets, and apply time-frequency analysis to SAR images of moving targets.
