摘要 本文给出一种基于机载单天线SAR实际数据进行ATI动目标检测的方法 .该方法将单通道SAR数据抽样近似为两通道ATI SAR(AlongTrackInterferometricSAR)数据 ,利用两通道方位向干涉进行杂波抑制 ,实现动目标检测 .检测结果表明 ,单天线SAR数据的ATI方法对动目标检测是有效的 ,在没有ATI SAR实际数据情况下 ,为研究ATI SAR干涉算法提供了一种有效途径 . In the paper,a new method of moving target detection for single-antenna airborn e SAR real data is proposed.The method samples the real data of single-antenna SAR into the data of two-antenna ATI-SAR.The ATI is adopted to suppress clutte r and to detect moving target.The detection results show that the method is effe ctive for moving target detection,and it provides an effective way to study ATI -SAR interferometric algorithm in absence of ATI-SAR real data.
