<p>PROBLEM TO BE SOLVED: To solve the problem of low reliability of correlation result due to conducting of gate processing, having a fixed size in correlation processing of a tracking radar with an automatic tracking track, in spite of the fluctuations in tracking precision due to proficiency of an operator or the video state, when executing semiautomatic tracking by the operator to the video display of a search radar, in the case of joint use of the search radar and the tracking radar. SOLUTION: Observational precision of the semi-automatic tracking track of the search radar 1 formed by the operator is measured, based on the automatic tracking track of the tracking radar 4 to a known target, to thereby constructing a database 12. Observational precision, corresponding to a tracking condition, is extracted from the database 12 at the actual using time; updating by a Kalman filter is executed, by using detection data inputted by the operator; a variable correlation gate, based on the error evaluation quantity of semiautomatic tracking track calculated there, is formed, to thereby execute the correlation processing with the automatic tracking track.</p> |
