[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0051] Aiming at the dimensional characteristics of the noise subspace of the polarization sensitive array, the present invention proposes a method for estimating the number of information sources suitable for the polarization sensitive array, which can realize the estimation of the number of information sources under the coexistence of white noise and uneven color noise. Noise environment close to actual engineering application. First, perform eigen-decomposition on the covariance matrix of the data vector received by the polarization sensitive array, and the number of eigenvalues obtained is twice the number of array elements, and the eigenvalues obtained are arranged in descending order, and the latter half of the small eigenvalues are used to correspond Construct the projection matrix with the eigenvectors of, and then reconstruct the new covariance ma...
