On performance of array signal processing

Published

Journal Article (Academic article)

A unified treatment for performance evaluation of various array signal processors involving waveshape estimation is presented. Detection performance is expressed in terms of the parameters of the power-type receiver operating characteristic (ROC) for optimum, beamformer, and null-steerer detectors. Estimation performance is analyzed in terms of the normalized mean-square error (MSE) for minimum mean-square error (MMSE) and maximum-likelihood estimator (MLE) under a varying noise environment. Sensitivity of the detection/estimation performance to the varying internal and directional noise sources is investigated. An inverse relationship is derived between the normalized MSE of the MMSE estimator and the power-type ROC parameter for the optimum detector
