<p>PURPOSE:To shorten the time required for identification and to improve target identifying ability by considering the position data and the doppler data of target detection data, obtaining not only the correlation of the target positions but also the correlation of target range changing rates, and narrowing the track. CONSTITUTION:A target-position-correlation processor 2 receives target detecting data such as position, doppler data and the like from a laser signal processor 1. The correlation probability of the target position is computed based on the target detection data and a predicted target position. A target-range-changing-rate-correlation processor 3 computes the correlation probability of the target-range changing rate based on the target detection data and the predicted target position. A target-track judging device 4 judges the target track based on the target-position-correlation probability and the target-range-changing-rate-correlation probability. A target-position predicting device 5 and a target-speed predicting device 6 predict the position and the speed of the present target based on the result of the target track. When it is judged that the track is established with the result of the track, the judging device 4 outputs the predicted target position and the predicted target speed into a target tracking device 11 and a track displaying device 12 through first and second switching circuits 7 and 8.</p> |
