A study of retrodirective array performance in the presence of multipath

The paper attempts to analyze the performance of a heterodyne phase conjugate retrodirective transceiver for full duplex communications in the presence of multipath signals and amplitude and phase perturbations across a four element antenna array. Simulation results are given and it is shown that the retrodirective array improves multipath fading in a full duplex scheme even under amplitude and phase imperfections across the array.
