Analysis of Phase-Conjugating Arrays in Multipath Environments

The ability of a phase-conjugating array (PCA) to reduce fading in single-reflector, dual-reflector, and blocked-line-of-sight multipath environments is presented. Compared to a reference four-element antenna array, the PCA improves worst case signal fading by as much as 39 dB. Agreement between the experimental results and a ray-tracing model is observed, verifying the model as a viable method for characterizing array performance in multipath environments.
