基于数据链的飞机空中进攻作战协同距离部署

Cooperative distance deployment of aircraft in combat based on data link

研究了空中进攻作战时战术协同数据链环境下的飞机距离部署问题。以Petri网作战模型为基础,构建了系统的信号流图结构,通过分析信号流通的总增益,得出了系统增加的作战能力单位与单项性能提升率的函数关系。以雷达探测面积变化比来表示单项性能提升率,并给出了双机同向直线、同向并行飞行时的计算方法,进而建立了机间距离与作战能力的映射关系。算例分析表明,前者作战能力随机间距离增加而提升,后者在雷达搜索方位角不同时,系统增加相同作战能力所需的机间距离也不同,且会出现双值对应的情况,为科学作战提供了理论指导。

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 improve ment 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 fat ter, 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.
