摘要
The influence of errors in the signal model using the methods of estimating the spatial spectrum of the input field of the antenna array is investigated. It is shown that, in the presence of model errors, the eigenvectors of the matrix of the mutual power spectral density of the sum of the signals and noise in terms of their stability and resolving power can differ significantly from each other. The use of a priori information on the number of signal sources in a given range of angles of their arrival makes it possible to construct an algorithm having a high resolving power in estimating the angle while maintaining its stability.
