INVESTIGATION OF PHASED ARRAY TECHNIQUES.

Abstract

This report describes a new technique for phasing a receiving antenna array. The method uses an acoustic analog of the antenna array to rebroadcast ultrasonic pressure waves in a transparent liquid medium (water). The contents of the medium are read out with a set of coherent optics. The readout mechanism contains a display which permits the bearing angle, radial velocity and time of occurrence of any target within the coverage region of the antenna array to be obtained. The system permits any number of these to be read out simultaneously, with no further adjustments or variation within the phasing mechanism. This report discusses the operation of the system, the limitations relevant to systems applications, the experimental verification of its basic principles, and a prognosis of the feasibility of extrapolating these techniques to large scale systems.
