摘要
合成孔径雷达回波模拟技术在SAR系统的研制、SAR图像处理等方面具有十分重要的作用。目前对于SAR回波模拟技术的研究还不够深入。针对该问题开展SAR回波模拟方法研究,通过对合成孔径雷达基本原理的分析及回波信号数学模型的推导,提出了一种较为通用的合成孔径雷达回波模拟方法,根据该方法采用Matlab进行了不同类型SAR回波模拟仿真试验。试验结果表明:该方法适用于单点目标、多点目标、面目标、分布目标及真实场景等多种类型的SAR回波信号仿真,对SAR系统设计及性能分析具有重要的参考意义。
Synthetic aperture radar echo simulation technology in the development of synthetic aperture radar system and in the subsequent processing of SAR images plays an important role. For synthetic aperture radar echo simulation technology research is not deep enough. SAR echo simulation study for the problem and through the analysis of the basic principle of synthetic aperture radar echo signal mathematical modeling of deduction, a more general synthetic aperture radar echo simulation is proposed, according to the method of using matlab to simulate different types of SAR echo simulation test. The test results show that the method is suitable for the single point target, more goals, objectives, distribution and the real scene, and other types of SAR echo signal simulation, for SAR system design and performance analysis has important reference significance.
