The problem of radar signal processing in the intelligent system of air objects recognition is considered in the given paper. This work is devoted to the development of signal processing technology based on the mathematical tools of predicate algebra. A method which allows to observe the dynamics of changes in image over several reviews radar is proposed. A model in the form of discrete samples – elements of processing in range and azimuth is presented. System of predicate features is introduced to describe the situation of the analyzed processing element. The decision on air object recognition is made from the analysis of the dynamics behavior of predicate features in the processing element.
