| 摘 要： | 提出了一种基于矩阵思想的雷达回波模拟方法，它采用一定的近似处理，可以高效的模拟出不同目标的原始回波数据，同时也能模拟出不同极化特性的场景的合成孔径雷达原始回波数据。该方法将飞行参数与地面参数的模拟进行分离，有利于实时计算。最后，用该方法对不同极化性质的地面目标进行了模拟。并给出了一些典型的目标回波的模拟效果。

| Abstract: | A method of SAR raw data simulation based on matrix is proposed.This method divided the simulation to two parts: the object matrix part and the carrier parameter part.The simulation is based on some approximation of the track of the carrier and it can simulate some kinds of the object surface very effectively.It can also effectively simulate the multi-polarization reflect signal of SAR.The division of the two parts helps the simulation easy to modify.Finally,some results of the simulation of multi-polarization raw data are given. |
