Abstract:

Distance deployment of two aircraft in combat with cooperative tactics data links is studied. On basis of the combat model described by Petri net, the signal flow chart structure of air combat is constructed. By analyzing the whole gains when the signal flows, the function equation between combat ability units and the single improvement ratio is obtained. The radar detection area variety ratio is made to represent the single improvement ratio, whose computation methods are evolved in two cases of two aircraft’s flying in the same orientation，in line or in row. Furthermore, distance’s connection with combat ability is built. Example analysis shows in the former case, combat ability will improve with increasing of distance between two aircraft, while in the latter, in case of different radar search azimuth angles, distance is different even if there is same added combat -ability in the whole combat system. Besides, it appears that one combat ability value is corresponding with two different distance values, which provides theory guidance for scientific combat.
