The Jamming Evaluation System of Intelligent Electromagnetic Spectrum Warfare

The jamming evaluation system of intelligent electromagnetic (EM) spectrum warfare (EMSW) is proposed. Firstly, the definition, characteristics, current situation and existing problems of EMSW are produced. Then the jamming classification, the principle and algorithm of the EMSW are analyzed from the aspects of jamming energy, generation path, generation mechanism, spatial location relationship, and so on. And the jamming evaluation system of intelligent EMSW is proposed, including the following six factors: 1) radar detection time delay ratio; 2) detection distance difference ratio; 3) working mode conversion ratio; 4) signal-to-noise ratio; 5) signal frequency alignment ratio; 6) signal alignment ratio. Finally, the anti-jamming measures are taken for traditional radar and phased array radar from three aspects: time domain, spatial domain, and frequency domain.
