摘　　要：根据线性调频中断连续波(FMICW)特点,设计高频地波雷达波形参数,实现对对象距离、速度和目标的探测,环境噪声和外部干扰频率直接影响雷达工作频率质量。研究了采用带通采样的方法,实现HF雷达噪声频谱在线监测的原理,以及频谱监测的波形设计和系统实现。使用浙江舟山实验数据进行在线处理,为雷达选择优质工作频率提供了依据,证明方法可行。To detect the distance and speed of target, the wave shape parameter of a high frequency ground wave radar (HFGWR) may be designed by using FMICW. The quality of radar work frequency is influenced severely by the frequency of the environment noise and the external disturber. In this paper, an online inspecting scheme of noise is introduced by employing the band sampling method, and the design of wave shape and the implementation of HF radar system are presented. The feasibility of method presented is confirmed by online data processing of a HFGWR located at Zhoushan, Zhejiang of China.
