| 摘 要： | 机载SAR回波数据是机载SAR信号处理的基础,但靠挂飞实验得到的数据价格昂贵且不灵活,也无法分析载机平台运动变化或雷达参数变化对整个SAR系统的影响.针对这一点,本文叙述了回波数据模拟的点目标理论模型并提出了二维SAR回波数据模拟的方法,给出了模拟实验的结果.并举出了这种回波数据模拟的一种应用,既通过点目标模型观察载机加速度误差对成像质量的影响.

| Abstract: | Airborne SAR raw signal is the foundation of airborne SAR signal processing,but the data got by flight experimentation is expensive and unflexible, meanwhile, the effect of flight movement and radar parameters related with SAR system can not be analyzed. This paper discusses the point object raw signal model and the method of SAR backwave data simulation,and the results of experimentation are given. Taking the application of backwave data simulation as an example, By the model of point backwave,the effect of image quality related with plane acceleration errors is observed. |

| Keywords: | synthetic aperture radar simulation of raw signal error of acceleration image quality |
