An Ultra-Wideband High-Isolation Single-Antenna Full-Duplexer Based on Dual-Phase Cancellation [PDF]
RadioengineeringWideband transmit–receive shared-antenna full-duplexers are a key technology for radar, communication, and electronic countermeasure systems. In special scenarios such as retrodirective cross-eye jamming, RF systems must adopt a TR shared-antenna ...

Investigations of Retrodirective Array Transponders.
, 2003 Retrodirective arrays, when illuminated by an interrogator signal, transmit a signal back towards the interrogator in the same direction as the incoming signal, without any prior knowledge of the source direction.

Phase‐conjugating retrodirective cross‐eye jamming [PDF]
, 2020 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 ...
