<p>PURPOSE:To increase a processing speed by judging that >=2 aircrafts are approaching mutually and outputting a warning from a warning output part when the aircrafts are registered in the same storage area. CONSTITUTION:Position information of an aircraft which is outputted from a radar 1 is digitized through a radar connecting device 2 and a digitization processing part 4 and a control means 19 finds the position coordinates of the aircraft A based on the output of a tracking process part 6, so that the aircraft A is registered in a matrix area 12 corresponding to the position coordinates. In this case, 1 is added as a registration number to the 1st area 13 in the area 12, the aircraft A is registered in the 1st detail area 17 in the area 12, and then the presence of the aircraft A is registered in the 2nd detail area 18 in the area 12 corresponding to a unit space where the aircraft A is expected to be a certain time later. If there is an unprocessed aircraft B, it is processed similarly to the aircraft A. Thus, all aircrafts are processed and a table 11 is searched 22 to output a warning from the warning output part 8 if there is an area 12 in the table 11 where >=2 aircrafts are registered.</p> |
