摘　　要：空载合成孔径雷达系统的研制过程中常需要对某些关键算法和功能原理进行验证,而这些验证用的数据又不可能完全通过代价昂贵的实际飞行获得,因此通过半实物仿真和信号模拟来获得所需的目标回波数据成为一个有效的解决手段。The imaging processing of spacebome and airborne synthetic aperture radar（ SAR） is a sophisticated system engineering. Many key algorithms and function need to demonstrate during the SAR system development. But it is impossible to acquire all the test data by expensive flight, especially for a spaceborne SAR. Usually an effective approach to get the verify echo data by hardware - in - loop simulation and target echo signal simulation.
