Abstract: The relevance of the research topic is due to the presence of inconsistencies of pragmatic and scientific character. The inconsistency in practice lies between the need and the possibility of improving the characteristics of an onboard radar station (BRLS) of a fighter to recognize the states of group air targets (MCC) and the insufficient level of its algorithmic support. To improve the information capabilities of the fighter radar, the article solves an urgent scientific problem, which is to develop a method for recognizing the states of the MCC that takes into account a priori information about their change. In accordance with the theory of systems with a random hopping structure, a new decision rule (algorithm) has been obtained, which is the novelty of the developed method. The simulation results of this algorithm indicate an increase in the probability of correct recognition by 15%.

Keywords: clustered air target, identification method, random jump structure system.
