PURPOSE:To improve the tracking accuracy in the implementation by arranging a number of predicting devices suited to the kinematic property of a moving object as tracking predicting equipment for tracking. CONSTITUTION:Distance and azimuth R and theta of a target detected with a radar receiver are stored temporarily into a buffer 1. Correlators 2, 4 and 6 compare values RP and thetaP forecast with predicting devices 3, 5 and 7 in terms of separate predicting characteristics with the target data R and theta stored in the buffer 1 and if the input difference is within the allowable range, the one in the line having the corresponding allowable range among the predicting devices 3, 5 and 7 performs a predicting computation based on the target data R and theta correlated to each other and outputs the results of the prediction to a tracking performance comparator 8. On the other hand, the target data from the buffer 1 are stored into a tracking information memory 9. The tracking performance comparator 8 compares outputs of the predicting devices 3, 5 and 7 in the respective lines with the target data stored in the tracking information memory 9 to select the data with the best tracking accuracy. |
