为使雷达回波模拟系统能够逼真地模拟真实作战环境,有效地对雷达各分系统进行测试,提出了雷达状态参数采集电路的设计方案,并给出了其软硬件实现;该方案以FPGA为核心,解决了不同状态参数的实时性采集问题,并通过制定串行传输协议,避免了数据传输过程中的冲突,保证了各状态参数传输的准确性,输出接口采用LVDS标准接口,确保了各状态参数的高速长距离传输;实验结果表明,该系统工作稳定,能够准确、实时地采集并传输雷达状态参数,且便于与其他数字电路的集成,满足系统设计的要求。

In order to simulate the radar echo realistically to the real operational environment, effectively to test various radar subsystem, the design scheme of radar status parameters acquisition circuit is proposed, its implement of software and hardware is given. The scheme, FPGA as the core, solved real--time acquisition issues of different status parameters, it avoided conflicts during data transmission through the development of a serial transfer protocol, which ensured the accuracy of transmission parameters. Employing LVDS standard in- terface as the output interface ensured the high--speed long--distance transmission of the status parameters. Experimental results show that the system is stable, it can accurately acquire and transmit radar status parameters in real--time, and easy integration with other digital circuits, which meet system design requirements.
