The effect of the character of the noise field upon the error in the optimum gain of an antenna array

Precise estimates were previously obtained for the error in the optimum gain of an antenna array arising from errors in the measured noise covariance matrix. It was observed that the error estimates are a function of the character and spatial distribution of the noise field. The purpose of the current work is to analyze this dependence of the previous results upon the quantitative and qualitative aspects of the noise field.
