Abstract	Due to the additional degrees of freedom, multiple-element cross-eye jamming (MCJ) can reduce the tolerance sensitivity and increase the effective sector angle. Considering MCJ ignores the retrodirective implementation, we investigate multiple-element retrodirective cross-eye jamming (MRCJ) against the amplitude-comparison monopulse radar in this paper. The monopulse ratio for MRCJ is derived under a classical jamming scenario, and two kinds of the indicated angle are presented by assuming a linear relationship between the monopulse ratio and the indicated angle. Linear-fit analysis is performed to define the cross-eye gain of MRCJ by introducing the linear approximations into the sum- and the difference-channel patterns. Simulation results demonstrate that most of the conclusions of two-element retrodirective cross-eye jamming (TRCJ) can also be drawn by MRCJ. Moreover, excellent performances of MRCJ in aspect of the tolerance requirements are illustrated.
