摘　　要：为满足雷达整机测试和应用条件下信号处理机多程序远程快速切换的新要求,提出了一种RS422远程控制方法,实现了经典FPGA+DSP架构雷达处理机多程序快速重启切换。试验结果表明:该方案具有可靠性高、软硬件改动量小的特点,且单芯片程序切换时间不超过5s。In order to meet the new requirement of multiple programs remote-quick switching for signal processor in radar test and application,a remote control method based on RS422 interface is proposed.The typical FPGA+DSP architecture is adopted to realize the quick restart and switch of multiple programs of radar processor.The test results show that the method has the advantages of high reliability and small changes of the hardware and software.The programs switching time of single chip is less than 5 s.
