Description: As a rule in the solving problems of a secondary radar processing a type of target maneuver is unknown. Therefore synthesis of adaptive trajectory filtering algorithms has important practical value. The possibility of increasing of efficiency of target tracking by adaptive correction values of the correlation matrix of measurement errors and estimations of parameters of the maneuvering target trajectory are presented in the article. The devices block diagram that realizes the adaptive algorithm of secondary radar processing is proposed. The algorithm of processing includes procedures for early detection maneuver of the target and evaluation of its intensity.
Keywords: radar data, measurement error, Kalman filter, maneuvering target, adaptive algorithm, the correlation matrix
