Abstract

Abstract:

To overcome the shortcomings of the conventional method for moving target detection in single-channel SAR, a method for moving target detection in single-channel multi-band SAR is presented. In this method, the stationary clutter could be eliminated by using the data of the equivalent dual-channel, which is constructed by desampling the original SAR data in the azimuth direction. Then moving target detection, parameter estimation and location are accomplished with the Keystone method. Moreover, a parameter optimization method in the multi-band SAR system is presented, which could solve the problem of blind area in the velocity detectable in the traditional SAR moving target detection system. As a result, the bands utilization and moving target detectable alarm increases greatly. Finally, simulation results are presented to demonstrate the effectiveness and feasibility of the proposed method.

Key words: synthetic aperture radar (SAR), moving target indication, single-channel multi-band
