本文提出了一种用于干涉合成孔径雷达（SAR）的时域（TD）原始信号模拟器。我们考虑的情况下，星载合成孔径雷达工作在条带，聚光灯，和混合模式，但机载合成孔径雷达的情况下，可以被认为是。星载平台被认为是在其标称（开普勒）轨道上运行，目标位于椭球地球上。我们描述了一个准确的TD模拟器，突出其有用性，在研究上的SAR脉冲响应和图像上的目标有限的扩展，由于操作条件不同的标称。
In this paper, we present a time-domain (TD) raw signal simulator for an interferometric synthetic aperture radar (SAR). We consider the case of a spaceborne SAR operating in stripmap, spotlight, and hybrid modes, but the case of an airborne SAR can be considered as well. The spaceborne platform is considered as traveling on its nominal (Keplerian) orbit, and the targets are located on an ellipsoidal earth. We describe an accurate TD simulator, highlighting its usefulness in studying the effects on the SAR impulse response and on images from targets with limited extension due to operational conditions different from the nominal one.
