Resolving Power of an Optimum Array Processor

Abstract

The classical concept of resolution consists of recognizing that an observed effect is due to two separate sources. The resolving power of an optimum array processor which is based on the inversion of the signal-plus-noise cross-spectral matrix is examined. Exact conditions are presented for resolution of closely spaced sources by an optimum beamformer. These results are applied to a line array and compared with the resolution capability of a conventional beamformer. For equal strength sources it is found, for example, that an output signal-to-noise ratio of about 47 dB is required to achieve a resolving power with an optimum processor which is ten times that given by the classical Rayleigh limit. Conditions are also presented for the resolution of two sources of unequal strength. It is shown that two closely spaced sources of unequal strength will be resolved by the optimum beamformer if the strength of the weaker source is slightly larger than that required for resolution of two equi-strength sources in the same geometric configuration.
