摘要
本文叙述了连续波多普勒雷达和多普勒信号模拟器的工作状态,着重分析了多普勒信号模拟器的工作原理、特点及影响其性能的因素。该模拟器可对10～0.8 cm波长的连续波多普勒雷达进行检测,经对X—波段的内、外弹道测速雷达、640测速雷达、汽车测速雷达及K_a—波段的测速雷达的实测,效果比较满意。该模拟器与同类产品相比,具有设计思想巧妙、功能完善、性能可靠、结构新颖、通用性强和使用简便等优点。
Presented in this paper is a novel Doppler Signal Simulatorworking with a CW Doppler radar. The operation principles,the characteris-tics,the performances and some influential factors have been analyzed in de-tail. The simulator can inspect the CW Doppler radar of 10～0. 8 cm wave-length with S、C、X、K_u、K、K_a bands and so on. The results tested in the interiorballistics, exterior bellistics and the 640 Doppler radar velocimeter of X-bandas well as the Doppler radar velocimeter of K_a-band are quite satisfactory. Thesimulator is characterized by its skillful design, multiple functions, reliableproperties, novel structure, universality and simplicity.
