Method for conducting array corrction and information source direction finding by using high precision auxiliary array element

The present invention discloses a method of spectral estimation for super-resolution spatial array source corrected with high accuracy by finding auxiliary array element, the array spatial orientation dependent influence of the error on the array steering vector is a diagonal matrix and error without error guide the product of this feature vector. First, using the direct method of measuring the array manifold a small number of adjacent array elements (≦ 3) accurate correction; secondly configured with an array azimuth error correction dependent cost function, and re-configured array steering vector; Finally array of azimuth-dependent characteristics of the error All other orientations dependent on accurate estimation of the array elements and the azimuth error is corrected. The method proposed by the present invention is a robust, easy to implement engineering, and enabling the estimated position error and orientation dependent, while the orientation can be widely used in large phased array radar, communications and other dependent error correction signal source and high-precision positioning has practical application value.
