二维旋转相控阵雷达内嵌式目标模拟器设计与实现

Design and realization of an embedded target simulator for 2D rotating phased array radar

论述了二维旋转相控阵雷达目标回波信号的一种模拟方法。介绍了雷达回波信号模型,给出了目标各种航路的产生方法,设计了一种内嵌式目标模拟器,能够实时产生和差波束回波信号输入到雷达处理通道中,实现雷达系统在不具备实际接收前端的情况下对雷达后级的调试,为雷达系统的性能验证提供有效的手段。

A method of simulating radar echo signals is discussed for the 2D rotating phased array radar. The echo signal model is introduced,and the method of generating target tracks is given. An embedded target simulator designed can generate the sum and difference beams in real-time and input them in the processing channel,and that makes it possible to test the radar system with no actual receiving front-end involved,which provides an effective means for the performance evaluation of radar system.
