摘要
Abstract
The transponder deception jamming with DRFM(digital radio frequency memory)is highly coherent with real radar echoes,which makes it difficult for radar to distinguish real radar echoes and jamming.To address this issue,a DRFM-based deception jamming detection method based on Hough transform was proposed.The jamming signal model based on linear frequency modulation was established and the spectrum of the jamming harmonics was analyzed subsequently.Then,the short-time Fourier transform and two-dimensional constant false alarm rate detector were used to extract the features of the jamming signal.The Hough transform was used to complete deception jamming detection.The proposed method is based on the characteristics of DRFM deception jamming itself,and does not depend on prior information and application scenario.Moreover,it has low computational complexity and good detection performance under the condition of low signal-to-noise.The effectiveness of the proposed method is verified through simulations.关键词
