地杂波背景下运动点目标的SAR成像算法

The SAR imaging algorithm of moving spot targets in the background of ground clutters

以理想面目标回波作为地杂波的近似,对面目标特征、面目标回波信号及其处理进行了分析,给出了以面目标为背景的运动点目标SAR成像算法,通过具体实例模拟仿真出独立运动点目标的SAR成像图和以面目标为背景的运动点目标SAR成像图。

With the echoes of perfect plane targets taken as the approximation of ground clutters, the characteristics and echoes of plane targets and the processing of the echoes are analyzed. The SAR imaging algorithm of moving spot targets in the background of the plane targets is presented. Simulations are made to get the actual images of independent moving spot targets and the moving spot targets in the background of the plane targets.
