针对高频地波海态雷达的特点以及雷达远程监控的需求，提出了一种基于DSP和CPID技术的雷达发射机监控系统设计方案，详细介绍了发射机监控系统的软硬件设计。该监控系统用于实时监测高频地波雷达发射机的运行状态和发射波形，对发射机实施自动故障检测与远程控制。本设计中利用DSP完成高速数据采集与处理，利用CPLD完成高速串行数据通信；采用了间断采集、连续传输的方法对发射机进行监测，降低了串行通信传输的数据量，进而保证监测与控制操作的实时性。

According to requirements of remote monitoring ,a monitoring and controlling system of radar transmitter based on DSP and CPLD is designed in this paper ,which is used to monitor the characteristics of high frequency ground-wave radar transmitter. The functions of this system include detecting the operation parameters of radar transmitter, detecting the transmitted waveform , fault diagnosis and remote controlling. The design of software and hardware are descried. The DSP is used in designing high-speed data sampling and processing module. The CPLD is used in designing remote real-time serial communication. In the design, sampling is discontinuous but transfer is continuous, which ensures real-time monitoring and controlling of radar transmitter.
