Resolution of Ambiguity for Randomly Moving Line Array.

Abstract

The generalized likelihood ratio detector, for deciding between the right-left ambiguity of a line array attempting to estimate the angle of arrival of a plane wave, is derived. Two scenarios are considered, the first with noisy measured antenna angle, the second with noiseless antenna angle measurements. The detector for both cases is a cross-correlator of the sample ac components of the measured antenna and source angle waveforms.
