Phase Synchronizing a Nonrigid, Distributed, Transmit-Receive Radar Antenna Array

A means is described for self-organizing a nonrigid, distributed, transmit-receive antenna array for use in airborne radar. The techniques are applicable to ground-based or shipborne radar as well. Methods are described for initializing the array using various primary microwave illuninators. The description of phase conjugation techniques and means for distributing phase reference to all elements in the array are the central parts of the paper.
