Abstract

We present two extensions of MUSIC to the case in which the steering vector is imprecisely known and show that the extended methods lead to the same direction-of-arrival (DOA) estimates as MUSIC. This somewhat surprising result provides a more general motivation of MUSIC than those currently available and shows that MUSIC possesses a certain degree of inherent robustness to steering vector errors.
