The subject of research is the statistically optimal methods, algorithms and devices for spatio-temporal processing of stochastic signals in onboard radar systems with antenna arrays and synthetic aperture. The aim of the study is to develop the theory and fundamentals of the technical implementation of cognitive radar systems for the formation of high-precision radar images in an extended field of view from aerospace carriers. The intermediate report for the second stage of the work contains mathematical models of spatiotemporal stochastic signals, fields and noise in multichannel radar systems and the results of the analysis of their statistical characteristics. Synthesized and investigated methods for optimal spatio-temporal processing of stochastic signals that are observed against the background of the internal noise of the receiver and the presence of interference. Recommendations for the synthesis of adaptive decorrelating filters in the presence of a database of radar images of the observation area and the spatial positions of sources of interference are developed. The dependences of the boundary measurement errors on the degree of decorrelation are studied. Based on the obtained methods and algorithmic operations, a block diagram of a multi-channel adaptive onboard radar system has been developed. Product Description popup.authors Inkarbaieva Olha S.
