Research Of Jamming Against PRC-CW Radar

In modern war, electronic warfare is one of the most notable features. As one of themain battle targets, radar plays an important role in electronic warfare. Jamming andanti-jamming technology are the critical factors to win the war. With the stronganti-jamming capability, low probability intercept(LPI) and the ability of ranging andvelocity simultaneously, PRC-CW radar is widely used in engineering application.Therefore, it is of important engineering application value to study the jammingtechnique against PRC-CW radar.This thesis the background and present state of PRC-CW radar is analyzed firstly.Secondly, the generation, characters and application of pseudo random code(PRC).Meanwhile, modulation and demodulation for PRC-CW radar signal is also discussed.Based on analyzes the principle of pseudo random code phase modulation(PRCPM)ranging, the PRC-CW radar ranging system is built on Simulink. Finally, several kindsof jamming technology for PRC-CW radar ranging have been studied, such as radiofrequency(RF) noise jamming, noise PM jamming, m sequence PM jamming, deceptivejamming based on PRC reconsitution, range-false-target jamming based on DRFM. Thesimulation result of each method is also presented.
