双基地武器定位雷达目标模拟技术研究

Study on Bistatic Weapon Location Radar Target Simulation Technology

本文从目标飞行特性,空间坐标转换,发射站、接收站和目标的空间模型,回波信号参数着手对双基地武器定位雷达目标模拟技术进行分析,提出在DBF接收阵列的分布式数字接收机中,采用数字中频模拟每个阵元接收到的目标信号从而实现系统目标模拟的方案,解决了双基地武器定位雷达调试和功能验证的一大难题,具有不需要辅助设备、可以动态模拟同时多批目标和便于系统状态监测等优点。

Bistatic weapon location radar target simulation technology is analyzed in this paper from target fly characteristic,coordinate conversion,space model of transmitter,receiver station and shell target,echo signal parameter;and then a new method is presented and can be used for the DBF receive array target simulation,in which digital IF is used for simulating echo signal in each distributed digital receiver.The method can solve the difficulty to debug and verify radar function of bistatic weapon location radar,and has many advantages including no requirement to other equipment,support multi-target dynamic test simultaneously and easy to monitor.
