Abstract:With the development of synchronization and high-performance computing technologies, the four advantages of bistatic/multi-static radar systems on anti-jamming, anti-destruction, anti-stealth targets, and anti-low-altitude target invasion have been gradually coming true. The bistatic/multi-static radar systems have attracted great attention. The bistatic scattering characteristics on Radar Cross-Section(RCS),scattering center,and polarization are quite different from the monostatic radar. Only baed on the detailed understanding of bistatic scattering characteristics, ?the bistatic/multi-static radar potentials in target detection,feature extraction,and target recognition can be fully exploited. The issue of bistatic scattering characteristics is one of the urgent problems waiting to be investigated. This paper reviews the newest development of bistatic scattering characteristics and attempts to guide future research on bistatic radar.
