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-DCNJ to control the distribution of jamming energy, which can present some particular deceptive characteristics. The relationship between jamming results and modulated noise is analyzed, based on which the procedure of generating the jamming signal is detailed, and the JSR performance is compared with the previous ones. Finally, the validity of the proposed method is demonstrated via numerical simulation.
