PURPOSE:To prevent automatically the influence of another target superposing on the aimed target and to continue stably the tracking, by providing an auxiliary radar tracking part for tracking another target appearing near the video of the target under tracking by a main radar tracking part. CONSTITUTION:A radar tracking system is provided with a main radar tracking part 16 which tracks the video formed by a target to be observed and provides the tracking data thereof to other associated apparatus, an auxiliary radar tracking part 17 which tracks once the video formed by the other target appearing near the target under tracking and provides the tracking data thereof to said apparatus, a signal processing part 15 which calculates the kinetic data of the respective targets under tracking, makes extrapolated prediction calculation in accordance with the results obtd. by such calculation and performs decision of whether the respective targets overlap on each other or not and the calculation for the timing when the targets overlap on each other and a control part 23 which changes over the inside parts of the respective tracking parts according to the signals from the respective parts. If the video of the other target having no relation with the target under tracking is to overlap on the video of the target under tracking, both targets are tracked by the respective tracking parts and the timing when the two targets overlap is decided from the obtd. tracking data. The predicted tracking is accomplished during said time. |
