PROBLEM TO BE SOLVED: To improve tracking computation accuracy without increasing the size of the shape of a radar.SOLUTION: A tracking system comprises: one transmission radar 30 for transmitting a radio wave 110 to a missile 100; a plurality of reception radars 20 (#1, #2) having different visual line directions for the missile 100, and for receiving reflected waves 120 (#1, #2) obtained when the radio wave 110 is reflected by the missile 100, respectively; observation means provided in each of the plurality of reception radars 20 (#1, #2) and each observing an azimuth, an elevation, a distance, and a Doppler speed of the missile 100 for the corresponding reception radar 20 on the basis of the reception of the reflected wave 120 by the corresponding reception radar 20; and tracking arithmetic means for performing computation for tracking the missile 100 in accordance with a non-linear estimation algorithm using information observed by each observation means.SELECTED DRAWING: Figure 1 |
