Online inspecting scheme of noises spectrum in the IF sampling radar

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.
