We present a new subspace-based direction of arrival (DOA) estimation algorithm for narrow-band sources with high-resolution localization capabilities. The algorithm is based on the invariance property of noise subspace to power of emitters. We speci2cally compare the resolution of the proposed algorithm with the well-known high-resolution multiple signal classi2cation (MUSIC) method. The proposed method performance is also superior to MUSIC algorithm in the case of correlated sources. Besides… CONTINUE READING
