一种非相参雷达回波信号模拟器的设计

分析雷达回波特性,从非相参信号模拟开始,提出一种雷达回波模拟器的实现方法。该方法可以利用已知或计算机产生的目标信息运算获得回波信号数据,通过FPGA或DSP芯片控制DDS产生中频回波信号。这种方法具有极大的灵活性和通用性,只要改变计算机回波信号计算模型或参数,即可实现不同回波信号的模拟。

Design of A Non-coherent Radar Echo Signal Simulator

Characteristic of the radar echo is analyzed;an implementation method of a radar echo signal simulator is presented for non-coherent signal simulation.By using this method,echo signal data can be obtained through computation based on known or computer generated target information;and intermediate frequency(IF) echo signal can be generated by DDS under the control of FPGA or DSP chip.The method features great flexibility and versatility,simulation of different echo signal can be achieved by merely changing computer echo signal calculation model or parameters.
