摘　　要：介绍了采用中频信号存储和DSP并行处理技术的试验平台和基于该试验平台的短波跳频信号侦察方法,不但能够实现常规定频信号的搜索截获和分析测量,同时可对跳频、突发等短持续信号截获和识别。能快速截获50跳/s的跳频信号并获取其完备的频率集,测频精度优于50Hz。The paper introduces a wide band reconnaissance system and a HF frequency-hopping signal reconnaissance method based on it. By means of IF data storage and muhi-DSP parallel processing, the system can capture HF frequency-hopping signal up to 50H/s and find its complete frequency sets. The accuracy of frequency measurement is better than 50 Hz.
