An design idea of real-time frequency spectrum detecting instrument’s signal sampling and processing system for the high frequency ground wave radar is presented in this paper,which based on Software-radio technology.Its kernel chip is DSP chip ADSP21062 and it develop a general and standard hardware platform.Experiments prove this can satisfy the requirement of real-time and high speed and display correctly the frequency of the testing signal;and it can detect four frequency segments,which meets the requirement of different detecting distances in radar.The frequency spectrum detecting instrument works at the same time with the radar,which entirely reflects the disturb to the radar,above all,it breakthrough the "time-sharing" localization in traditional instrument. 软件无线电 ADSP21062芯片 数字信号处理 数据采集 software radio ADSP21062 chip digital signal processing data sampling TN958 国家"十五"计划资助项目（2001AA631050） 2003-05-01 2021-04-01 5
