Real component effects on PON retrodirective array performance

We show how the positional accuracy of the re-transmitted signal from a PON retrodirective antenna array (RDA) is influenced by array size, array element type, LO phasing error, mixer leakage and conversion gain imbalance. Specific recommendations on the permissible tolerances allowable for these parameters are given in order to assist in facilitating design specification adherence. This type of antenna has application in a variety of situations where tracking of a moving target is a necessity. Most notable applications are tracking of low Earth orbiting satellites, terrestrial mobile communications, and vehicular telemetry.
