基于梳状谱调制和间歇采样重复转发的复合干扰

Abstract

Abstract:

The amplitude of false targets caused by interrupted sampling repetitive repeater jamming (ISRRJ) fades increasingly and the energy of false targets is dispersive. A composite jamming method based on comb spectrum modulation jamming (CSMJ) and ISRRJ is proposed. Firstly, the properties of CSMJ and ISRRJ are analyzed. Secondly, the characteristic of concentrated false targets caused by composite jamming is presented, and how to select parameters is deduced. Finally, the jamming effect of the new method is simulated. The theoretical analysis and simulation results demonstrate that the proposed method with brief parameters is feasible to cause concentrated false targets with uniform amplitude.

Key words: comb spectrum modulation, interrupted sampling, repetitive repeater, composite jamming
