Coherent Noise Synthesizer.

Abstract

A noise-generating algorithm and associated computer program for well-defined testing of beamformers are described. The algorithm is especially suitable for superdirective arrays of underwater hydrophones as it generates Gaussian noise of specified coherency. Statistical properties of the generator are confirmed to be those planned, and the ability of the generator to synthesize noise for isotropic or surface noise sources is verified for three-element arrays. Cumulative distributions for estimated coherency were obtained for the model. (Author)
