A self-survey technique for self-cohering of antenna systems

A navigation technique is applied to the location of the elements of a flexible phased array. The technique also calibrates the phase reference for each array element. The system requires several beacons of known position. The effects on beamformation of beacon position errors and of phase measurement errors (owing to multipath) are predicted. The conclusions are confirmed by computer simulation and by experimental self-cohering with a flexing four-element random array.
