Phase‐conjugating retrodirective cross‐eye jamming

Abstract

A cross‐eye jammer based on a phase‐conjugating (PC) retrodirective array is proposed. Such PC cross‐eye jammers eliminate the delay inherent in traditional Van‐Atta (VA) cross‐eye jammers and induce errors in radars that use the same antenna beam for transmission and reception, while VA cross‐eye jammers do not. Validated simulations are provided to confirm the effectiveness and retrodirective properties of the PC cross‐eye jammer.
