| 摘 要： | 介绍了自行开发的星载极化SAR数据计算机模拟系统，此系统采用的模拟方法遵循了星载极化SAR系统实际运行的情况，按发射脉冲时间序列，分别依次计算各发射脉冲相应的回波数据，与常用的以点目标为基础逐点模拟方法相比，计算效率高，现贴近实际系统，便于模拟各种误差的影响和保持其对所有目标回波影响的一致性和相关性。给出了星载极化SAR数据模拟的实例。

| Abstract: | This paper introduces a new Spaceborne Polarimetric SAR Data Simulation system, The siumlation method used in this paper is based on the view of real system; and according to the sequence of the transmit pulses, each return wave formed by the reflection of all the targets which are irradiated by the transmit beam is calculated one bye one, all these return wave data form the result. Compared with the usually used method based on single point target simulation, this method is much more efficient especially in case of simulating a large area. It is also conveniently to simulate all kinds of error and keep the correlation and consistency of the errors. At last, a simulation example is also given. |
