<p>PROBLEM TO BE SOLVED: To accurately specify a target position or a position track in three- dimensional space using a plurality of target observing devices by providing a target position correlator for performing correlation processing based on angle information or the position relationship of angle track, and others. SOLUTION: Target tracking devices 3 and 4 calculate target angle/angular velocity and generates an angle track for target angle information obtained by first and second target observation devices 1 and 2. A target position correlator 12 judges whether the angle track is correlated or not. A target distance calculator 13 calculates a target distance by the trigometry using angle track and position information inputted by a target observation device position element inputting device 5 according to the judgment. A three-dimensional polar coordinate calculator 14 calculates a target position in the polar coordinate system from the target distance, angle information, and device position and a three-dimensional rectangular coordinate calculator 15 transforms in to the rectangular coordinate system. A three-dimensional position correlator 16 judges whether the transformed data are correlated to, for example, an existing target and a three-dimensional integrator 17, for example, integrates the target.</p> |
