摘要

The motion of moving targets causes distortions in SAR image, which present a challenge on image interpretation. Comparing to stationary targets' signatures, signatures of moving target are distorted from azimuth displacement to smearing beyond detectability. In this paper, a moving target detection algorithm is proposed based on Polarimetric Whitening Filter (PWF) as well as Time-Frequency (TF) analysis. An experiment is implemented using multi-look X-band PolSAR image acquired by PiSAR. Both moving target and stationary target are included in the image. Results shows PWF method and time-frequency analysis could be used detect moving targets as respected.
