Abstract:Taking two ground-based meteorological radars as examples,this paper analyzes the generation mechanism of co-frequency asynchronous interference and co-frequency synchronous interference,and describes the characteristics of co-frequency asynchronous interference,co-frequency synchronous interference signal and meteorological echo of ground-based meteorological radar,so as to quickly and accurately identify the echo of co-frequency interference signal of meteorological radar and improve the effect of meteorological radar in business application,which could provide more support for the suppression of co-frequency interference of meteorological radar,and lay a solid foundation for further study and research on the suppression method of atmospheric environmental electromagnetic interference of operational meteorological radar.
