Performance analysis of multiple-element retrodirective cross-eye jamming based on linear array

Due to the additional degrees of freedom, multiple-element cross-eye jamming (MCJ) can reduce tolerance sensitivity and increase the effective sector angle. In this paper, we investigate multiple-element retrodirective cross-eye jamming (MRCJ) based on the retrodirective linear array. The monopulse error and cross-eye gain are derived via trigonometric approximations. Moreover, excellent performances of MRCJ in terms of induced angular error and tolerance requirements are demonstrated in simulation results.
