摘要
双站SAR是一种新体制SAR,它具有构型灵活多变、隐蔽性强等优点,在国防建设中具有重要的应用前景。双站SAR的同步误差和信号处理的复杂性给实际系统和成像处理都增加了困难。在X波段双站SAR一站固定模式的实验基础上,针对实际实验系统设计,对同步误差的产生和消除进行了分析,并利用BP算法对实验数据进行了处理。仿真和实际数据处理结果都证明了本次实验设计的有效性和算法的正确性。
Bistatic SAR is a new SAR system.Since it is flexible,and easy to hide,it will be helpful for national defense.The superiority also brings difficulty in synchronization error elimination and signal processing.According to the X-band one-stationary bistatic SAR experiment,this paper analyzes the design of the experiment and the origin of synchronization error and how to eliminate the synchronization error.Finally back projection algorithm is used to process the origin echo data.Simulation results and data processing results both verify the effectiveness of the design and the algorithm.
