Description
Summary:In this paper the algorithm of suppression correlated noise in adaptive antenna array is presented. During the work of active radar system with adaptive antenna array the reflections of the sounding signal from the clutter can be destroy the structure of spatial-time covariance matrix. If it is need a quick scan of the beam leads to the fact that the angular position of the reflectors is constantly changing, which makes applying to adopt a system of algorithms based on the selective treatment of the spatial covariance matrix. The suggested method is based on the idea of pre-decorrelation signal processing algorithm that using the weighted orthogonal matrices. A model of the processing algorithm of space-time correlated signals designed. The main algorithm's characteristics such as stability and noise immunity are investigated. It is shown that the proposed method does not reduce the effectiveness of the rapid scanning of the main beam antenna.
