A new parameters estimation approach for mixed sources is proposed in this paper, which is under the sparse signal reconstruction framework. By reconstructing of covariance matrix, directions of arrival (DOAs) in the far-field part were estimated with an l1-svd-like method directly. Then the subspace difference method was adopted to obtain the near-field covariance matrix, and the relative DOAs can...
A novel bind algorithm is proposed for ranges and direction-of-arrivals (DOAs) estimation of the hybrid narrow-band sources, which contain both the near field sources and the far field ones. To separate them, a two-step algorithm is exploited. In the first step, the far-field sources are identified by exploiting the MUSIC method. After eliminating the far field source components in the auto correlation...
Two novel algorithms which exploit the fourth-order statistics are proposed for DOA and range estimation of the near-field narrow-band sources. Compared with most proposed methods which can identify only p sources with a (2p + 1)-element ULA (uniformly linear array), the proposed methods can identify 2p or 2p - 1 sources with the same one. Moreover, our methods calculate much fewer fourth-order statistics...
Two novel algorithms are proposed for ranges, frequencies and direction-of-arrivals (DOAs) estimation of the narrow-band near field sources. By exploiting the time-domain and space-domain correlations of impinging signals jointly, we can identify 2p independent sources and estimate 3 groups of parameters with a uniformly linear array (ULA) of 2p + 1 elements, being double of the conventional methods...
