超视距空空导弹协同允许发射区解算方法

A Method for Calculating Allowable Launch Envelope of Over-the-Horizon Air-to-Air Missile

对协同制导条件下的空空导弹发射区解算方法进行了研究。首先,分析了飞机目标的RCS模型,研究了多机协同探测问题,根据目标和载机当前运动参数提出了导弹协同发射决策算法;然后,构建了具有约束条件的导弹和目标运动模型,提出了基于编队内切圆有界黄金分割搜索的方法,并对三种编队队形下的协同发射区进行仿真验证。通过与非协同制导下发射区的比较,结果表明编队协同制导能够使导弹允许发射区增加,高度协同和角度协同使得导弹允许发射区增加最明显。

A method for calculating air-to-air missile allowable launch envelope with cooperative was given. A classical fighter＇s radar cross section was analyzed at first, and multi-fighter cooperativedetection was studied. A new cooperative launch algorithm was presented based on the instantaneous states ofthe fighter formation and the target. Then the motion models of the missile and target with constraint condition was built up, a golden section-probability searching method based on inscribed circle of formation~ Simulation was made for study the cooperative launch envelope of three scenarios of formation, the result indicated that allowable launch envelope with cooperative guidance was expanded greatly.
