Abstract: In this paper, a new multi-loop reverse cross-eye jamming configuration is proposed, which is composed of four jamming elements arranged at unequal intervals in linear array. With the help of channel echo, vector synthesis and angle factor, the theoretical derivation and simulation verification of the decoy angle, decoy distance and parameter tolerance of the new configuration are carried out in details. The simulation results show that in Ku band, the new loop configuration mounted on a large platform can produce a large cross-eye gain, and guid the monopulse radar to generate a larger decoy distance and angle. In the case of given angle factor, with the increase of jamming distance and jammer angle, the contour of the angle factor decreases obviously, and the requirements for parameter tolerance of multi-loop reverse cross-eye jamming is becoming more and more stringent.
