多波段SAR系统动目标检测和参数优化设计
Moving target detection in the multi-band SAR system and parameter optimization
摘要
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 .关键词
