Approach estimation method of moving body



PROBLEM TO BE SOLVED: To make an approach estimation of a moving body processible in real time by carrying out a specific operation for judging distance to other moving bodies for every monitoring cycle, and by performing detailed approach estimation calculation only when the result of the specific operation is lower than a specified value for each moving body to be monitored. SOLUTION: The approach estimation of a moving body in aviation control or the like is made by, for example, an aircraft approach estimation processing 1 with a function such as a speed calculation part 2 and a detailed calculation execution judgment part 4. The speed of each air craft being indicated by the distance that aircraft travels within one cycle is registered on a speed table 3, where the speed is calculated by the speed calculation part 2 based on the position of each aircraft for every monitor cycle. The detailed calculation execution judgment part 4 obtains the sum of the scalar value of the speed of a specified aircraft and another according to the speed table 3, a detailed distance execution judgment table 5 is referred to, and subtraction is made from a set distance judgment value being set by a specific method in advance for updating. As a result, only for the combination of the aircraft where a prescribed value becomes 0 or lass, an approach estimation detail calculation part 6 performs a detailed distance calculation such as on the distance of an estimation position.
