On the sensitivity of covariance based direction finding to gain and phase perturbations
B. Friedlander · 1992
In recent work the author (1990) studied the sensitivity of two direction finding algorithms (MUSIC and maximum likelihood) to gain and phase errors. Here, he generalizes the analysis to any consistent estimator based on the covariance matrix of the received data. The analysis is deterministic in the sense that the gain/phase perturbations are assumed to be fixed during the data collection interval; also, the exact covariance matrix of the received data is assumed to be known.>
