Two-Dimensional Discretized Coherent Noise Jamming Method to Wideband LFM Radar

Abstract: Abstract-For coherent jammers to wideband linear frequency modulation (LFM) radar, the ratio between jamming energy and signal energy is always constant. To enhance the jamming to signal ratio (JSR), a two-dimensional (2D) discretized coherent noise jamming (2D-DCNJ) method is first proposed in this paper, where the covering area of the noise jamming results in 2D imaging is limited to a certain shape and further discretized to centralize the jamming energy. Moreover, the idea of weighting is applied to 2D-DCN… Show more

“…In recent years, with the development of digital radio frequency memory(DRFM) [4,5] technology, a jammer can rapidly intercept radar signals, modulate them, and forward them. For this reason, many new jamming styles have emerged, including shift-frequency jamming [6,7], interrupted sampling and repeater jamming (ISRJ) [8][9][10], and smart noise jamming [11][12][13][14][15][16]. The above-mentioned jamming methods are all coherent with radartransmitted signals and can obtain gain from matched filtering and pulse compression processing [17].…”
