Signal Processing for Very Large Arrays.

Abstract

This report deals with the use of many sensors grouped into two or more clusters (subarrays) for the determination of bearing and range to an acoustic source producing sinusoidal or narrowband Gaussian signals. The spacing between subarrays is typically very large compared with the acoustic wavelength, but the spacing between sensors in any one subarray is comparable with or smaller than the acoustic wavelength. The noise is Gaussian and spatially incoherent.
