<p>PURPOSE: To obtain a detection apparatus by which the position of an object (an airplane) as a jamming generation source and its track are estimated without using a sensor or a device for exclusive use and by using only various pieces of aviation log data collected in an air traffic control system in the present state. CONSTITUTION: ASR/SSR data which is sent from an aviation radar 1 is stored in an airplane-log-data storage device 4. A support processing device 5 judges, on the basis of airplane log data, whether every airplane is being jammed or not. The movement estimation positions of airplanes 100 which are judged to be jammed and whose number is (n) [(n) represents a natural number of 2 or higher] are computed at every rotation time unit of aviation radar 1. On the basis of the computed movement-estimation position in (n) pieces, their positions of the center of gravity are computed, positions of the airplanes as jamming generation sources are estimated, and tracks of the airplanes 100 as the jamming generation sources are computed on the basis of the time-series positions of the center of gravity. The positions and the tracks which have been computed are displayed on a CRT 7 or a printer device 8.</p> |
