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)
