【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.更多还原
