Abstract:Deceptive jamming is a common radar jamming technology. This paper presents a novel deception jammer against monopulse radar. First, the characteristics of angle deceptive signal is analyzed. Then, according to energy aggregation properties of the linear frequency modulation (LFM) signal in fractional domain, a digital radio frequency memory (DRFM) under compressed sensing (CS) framework is proposed in order to generate angle deceptive jamming signal. In order to achieve effective jamming against the monopulse radar tracking system, the angle pull-off jamming and glint jamming achieving method is considered by controlling the power of jamming signal. Simulation results show that origin signal can be recovered with the proposed method very well, and the jammer can achieve a stable angle pull-off and blink jamming. © 2017, Editorial Board of JBUAA.
