摘要
本文描述了星载合成孔径雷达(SAR)系统的数学模型及其计算机模拟;给出了距离迁移效应、距离迁移较正、方位加权、信号产生和处理和模拟结果。这些结果较逼真地复现了星载合成孔径雷达系统的动态工作过程;可用来进行星载SAR系统信号处理研究,评价系统性能,为系统优化设计提供依据。
The mathematical model of spaceborne SAR systems and its computer simulations are described. Results of computer simulations about range migration, range migration correction, azimuth weighting and azimuth signal generation/processing are given. This software can be used to simulate the dynamical process in spaceborne SAR system, to develop new signal processing technique and to evaluate the performance of the designed system.
