Abstract Noncircular polarimetric-MUSIC (Multiple Signal Classification) is herein proposed for Direction Of Arrival (DOA) estimation of rectilinear signals (such as AM, BPSK communications signals) by using one or a number of possibly defective (incomplete) electromagnetic vector-sensors. As an extension of the existing noncircular MUSIC, this new MUSIC variant can incorporate the redundancy in the nonvanishing conjugate moments and polarization diversity present in a polarization-sensitive array. It can also be directly extended to a defective acoustic vector array. Simulation results are given to validate the proposed method.
