T.-R. Chen, Zhe Zheng · 2024
Traditional noise jamming has high jamming power due to its incoherence with radar signals, which cannot solve the problem of low power effective jamming. Based on the smart noise jamming, this paper presents a time-domain convolution jamming method. The time domain convolution jamming can not only use the broadband jamming characteristics of the noise frequency modulation (FM) signal, but also use the pulse compression gain to reduce the jamming power. Meanwhile, we analyze the jamming mechanism of this method for pulse compression radar in detail, quantitatively analyzes the jamming characteristics and gives the optimal selection range of jamming parameters. The simulation results show that the method can effectively reduce the jamming power and achieve effective jamming to the pulse compression radar.
