<P>PROBLEM TO BE SOLVED: To perform accurate allocation to flight tracks by a high-resolution sensor and a low-resolution sensor to generate the true target number of flight tracks. <P>SOLUTION: A tracking device includes: a sensor 1 for observing targets to generate flight tracks; a sensor 2 having lower-resolution than that of the sensor 1, for observing the targets to generate flight tracks; a flight track allocation processing unit 3 for allocating the flight tracks generated by the sensors 1 and 2 on a one-to-one basis; a first flight track updating unit 5 for updating the flight tracks generated by the first sensor 1 on the basis of the corresponding flight tracks generated by the sensor 2 in accordance with the allocation result; a second flight track updating unit 6 for updating unallocated flight tracks generated by the sensor 1 on the basis of the plurality of flight tracks generated by the sensor 2 in accordance with the allocation result; a resolution ratio determination processing unit 4 for controlling the operations of the first and second flight track updating units 5 and 6 on the basis of a resolution ratio between the sensors 1 and 2; and a flight track update integration processing unit 7 for integrating the updated flight tracks. <P>COPYRIGHT: (C)2013,JPO&INPIT |
