摘要: 高稳定度的频率源是实现双站合成孔径雷达(BiSAR)系统相位同步的基础，该文研究分析了 收、发系统独立频率源条件下不同类型的频率误差对BiSAR成像的影响，确定了BiSAR成像的频率源稳定性要求。最后，给出了计算机仿真的结果。Abstract: The high stability of frequency sources is the foundation to the phase synchronization of the Bistatic Synthetic Aperture Radar (BiSAR) system. This paper analyzcs the influence of various frequence instabilities of sources in transmitter and receiver to the BiSAR imaging, and demonstrates the requirement to the source stability. The computer simulation results of BiSAR imaging with four types of frequency instabilities are presented.
