Considering passive noise decorrelation, a technique has been developed for assessing the presence of passive interference in radar channels. The proposed method provides a choice of the range interval of a particular method of forming a classified training sample generated only by the active noise. Methods are proposed for constructing noise suppression systems with structural adaptation of spatial filters in the time and frequency domain. The structural adaptation of the spatial filter eliminates the possibility of distortion of the main lobe of the antenna pattern beam in the case when the active noise during the scanning of the antenna is shifted from the direction of the side lobes to the direction of the main beam. This eliminates the possibility of deterioration in the accuracy of measuring angular coordinates and radar sensitivity. Multichannel parallel-serial signal processing using the Gram-Schmidt algorithm has been improved. The use of spatial, temporal, correlation, and spectral differences in the structure of signals and interference provided wider opportunities for providing noise immunity in difficult conditions of radar operation.  Product Description popup.authors Minzak Nataliia V.
