| Abstract: | By analyzing time-frequency characteristics of the pulse interference in the frequency monitor system (FMS) of high frequency radar, this paper gives a method to eliminate its effects. An OS (order statistics) arithmetic of two dimensions was used to estimate the noise floor under the intensent pulse interfrence in real-time and a double threshold method in amplitude and percentage was provided to detect the pulse interfrence. The application indicated that this method can greatly improve the performance of FMS. |
