2000 (English)In: Proc.of IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2000, V-3081-V-3084 p.Conference paper (Refereed)
We consider the problem of estimating the direction-of-arrival (DOA) of one or more signals using an array of sensors, where some of the sensors fail to work before the measurement is completed. Methods for estimating the array output covariance matrix are discussed and used for DOA estimation together with the MUSIC algorithm and with a covariance matching technique. In contrast to MUSIC, the covariance matching technique can utilize information on the estimation accuracy of the array covariance matrix, and it is shown that this can yield a significant performance gain.
