摘要
雷达杂波消除模块能最大限度降低杂波干扰,充分发挥雷达的工作性能。移动目标显示模块和恒虚警模块是雷达信号处理的两个主要模块。移动目标显示模块能成功分离雷达回波信号和干扰信号。分离出的回波信号有大量的残余信号,为了消除残余信号,必须对雷达信号进行恒虚警处理。借助FPGA开发工具,采用模型化方法设计雷达杂波消除模块,可以最大限度缩短设计周期、降低开发费用、节省硬件资源。
The radar clutter elimination module can reduce the clutter interference to the maximum extent and give full play to the radar working performance.Moving target display module and constant false alarm module are two main modules for radar signal processing.Moving target display module can successfully separate radar echo signal and interference signal.Separated echo signal has a large number of residual signals.In order to eliminate the residual signals,the radar signal must be carried out constant false alarm processing.With the help of FPGA development tools,the radar clutter elimination module is designed by modeling method,which can shorten the design cycle to the maximum extent,reduce the development cost and save hardware resources.
