编队歼击机超视距截击效能评估

应用兰彻斯特理论研究了编队歼击机超视距截击的效能评估问题.对照兰彻斯特理论假设条件与超视距截击背景,使用第二线性律与平方律分别描述了截击空战的探测阶段与射击阶段.以最大损失交换比为原则,将火力分配引入到评估模型中.利用机载雷达的探测概率与空空导弹的击毁概率,分别建立了每架飞机探测效能与射击效能的动态模型.算例表明,突击方护航歼击机的价值系数显著影响拦截方的火力分配,拦截方选择先攻击护航歼击机再攻击歼击轰炸机的战术,采取电子对抗措施,提高飞机生存力均可提高截击效能,该模型计算简便、合理有效.

Beyond visual range interception effectiveness evaluation of formation fighter

Evaluation problem of formation fighter’s beyond visual range interception effectiveness was studied by Lanchester theory. Comparing hypothesis condition of Lanchester theory with actual background of beyond visual range interception, detection and attack phases of interception mission were respectively described by secondary linear law and square law. On the principle of maximum commutative loss ratio, fire distribution was introduced into evaluation model. Dynamic models of detection effectiveness and attack effectiveness were established by using finding probability of airborne radar and hit probability of air-to-air missile respectively. A numerical example shows that value coefficient of assault side-s escort fighter significantly influences fire distribution of interception side, and interception side-s tactics selection attacks escort fighter first and then fighter bomber. Interception effectiveness could be improved both by using electronic countermeasure and enhancing fighter survivability, and the model is not only an easy calculation but also reasonable and effective.
