一种SAR/MTI雷达射频回波模拟器总体设计

Overall Design of a RF Echo Simulator for SAR/MTI Radar

近年来,随着SAR/MTI雷达在海湾战争中的成功应用,因其优越的战场感知能力引起了各国的重视,促进了新体制高性能多功能SAR/MTI雷达的技术发展和应用。雷达射频回波模拟器做为SAR/MTI雷达不可或缺的先进仿真测试手段也得到了广泛应用。本文给出了一种SAR/MTI雷达射频回波模拟器的总体和信号保真设计,具有较好的可扩展性,可通过软件功能部署和硬件配置重构实现不同类型雷达的回波模拟应用,具有一定的设计参考价值。

In recent years,with the successful application of SAR/MTI radar in the Gulf War,its superior battlefield perception ability has attracted the attention of various countries,which has promoted the development and application of the new system of high-performance multi-function SAR/MTI radar.Radar RF echo simulator is also widely used as an indispensable advanced simulation test method for SAR/MTI radar.In this paper,a comprehensive and signal fidelity design of a RF echo simulator for SAR/MTI radar is presented.It has good expansibility,which can be used to simulate different types of radar echo through software function deployment and hardware configuration and reconstruction.It has certain design reference value.
