An Approach on Parameters Estimation about Distributed Source

During parameters estimation of the distributed source, there are many errors if it is modeled as a point case in space. The generalized high resolution algorithms, estimating the distributed source parameters, normally demand complex computation, and the angular distributed function is known. To reduce the computational complexity greatly, the correlation algorithm is proposed for the coherent distributed source parameters estimation using the special geometry structure of signal receiving antenna array, and the ambiguity of DOA estimation is also analyzed. Computer simulation testifies the validity of this algorithm.
