The Wavelet-based RGPO Jamming DetectionZHANG Jian-jun,LIU Quan(School of Information Engineering,Wuhan University of Technology,Wuhan 430070,China)In the modern war,with the rapid development of electronic countermeasure technology,the radars of different systems would be suffered various kinds of jamming from enemy in the complicated electronic environment.RGPO is a kind of widely used active jamming with greater harmfulness.Jamming prompt and effectively must be detected in order to take the corresponding countermeasure to it.In this paper the basic principle of RGPO and the theoretical foundation of wavelet-based jamming detection were introduced,then the distance detecting model of radar was set up and the method of wavelet-based detecting RGPO was proposed.The simulation results indicated that the method can not only estimate the jamming effectively but also locate it accurately.wavelet analysis;range gate pull off(RGPO);jamming detection;anti-jamming
