OPTIMUM SIGNAL PROCESSING IN THE PRESENCE OF SPATIAL NOISE,

Abstract

An optimum signal processing theory for active radar (sonar) arrays is developed. Both discrete and continuous arrays (apertures) are considered. An optimum linear processor is developed which maximizes the output signal-to-noise ratio when the input is a known signal imbedded in correlated and uncorrelated noise. The signal processing theory requires a knowledge of some of the statistical properties of the noise field. Therfore, a stochastic representation for a general, polarized, nonisotropic noise process is formulated. This representation is used to determine the cross-spectral densities and cross-correlation functions between antenna array elements in the presence of the noise field only. (Author)
