<p><P>PROBLEM TO BE SOLVED: To provide rapid and more reliable control information to an air traffic controller. <P>SOLUTION: This air traffic control system has: a signal processing part detecting position information about a target object from observation data observed by an observation means; a first following processing part inputted with the position information about the target object in each observation period, detected by the signal processing part, and performing a following process about the target object from the latest position information about the target object and the position information about the target object which has been detected last time; and a second following processing part inputted with the position information about the target object in each observation period, and performing a following process about the target object from the latest position information about the target object and a plurality of pieces of position information about the target object, detected in the past. A processing result of the first following processing part is displayed on a display part, while a processing result of the second following processing part is inputted to the first following processing part to correct the processing result of the first following processing part by the processing result. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
