“…7, respectively. We can see that the first-order approximation of |φ r | in ( 13) is very close to the actual value of |φ r | in (9) and that the region in which |φ r | is maximized (the region of γ and δ for which |φ r | 15 • ) conforms to the principle based on which we find the maximum |φ r |, as in (14).…”

“…In previous analyses of RCJ and MRCJ, antenna polarization was not considered [1 -11]; therefore, the antenna insertion phase in the RL, which is strongly related to the antenna polarization [13,14], was also neglected. If the polarization of the transmitted radar wave varies in the 3 dB main-lobe, different insertion phases will arise on the two jammer antennas, thereby introducing an additional phase error into the 180 • phase shifting in the RL.…”

“…where θ is the azimuth angle and P A (θ), P B (θ), P C (θ), and P D (θ) are the patterns of the subarrays A, B, C, and D, respectively. Using the polarization angles (γ, δ) [14], the polarization of the transmitted radar wave in the 3 dB main-lobe of P tH (θ) is written as…”

This paper presents an approach for mitigating the cross-eye jamming using a dual-polarization array. By transmitting a sum beam and a difference beam in two orthogonal polarimetric channels, a synthesized transmitted beam with spatially varying polarization is produced, such that the polarization of the transmitted radar wave varies in azimuth or elevation. Thus, the phases of the signals received on the two antennas of a cross-eye jammer become unequal, and an additional phase difference is introduced to disrupt the 180 • phase shifting in the retrodirective loop of the jammer. By means of beam scanning in a small angular range, the optimal beam steering configuration can be found to maximize the phase error for the mitigation of cross-eye jamming. As a result, the jamming performance of the cross-eye jammer degrades largely. Theoretical analysis and simulation results indicate that the proposed method is valid and feasible.
