Abstract
An investigation of the effects of system and medium perturbations, and the deviations of signal field statistics from usual assumptions, on the performance of adaptive arrays is presented. The emphasis is placed on the determination of the sensitivity of the adaptive processors to perturbations, rather than its overall performance in a representative background. The numerical results are limited to CW signals, and a frequency domain element space adaptive beam-former is modeled for the majority of the results. Representative comparative results including frequency domain beam space, time domain element space, and matched array processors are also given.Keywords
