针对敌方存在伴飞诱饵情况下我方自杀式无人机的攻击策略问题展开研究。首先,根据自杀式无人机的作战特点,提出一种改进的Lanchester方程,即在分析机载传感装置作战性能的基础上,建立起作战双方兵力损耗的微分方程,以得到能够描述自杀式无人机的作战规律。然后,将最优控制方法应用于Lanchester方程中的攻击策略分析,以Lanchester方程为状态方程,以无人机的攻击概率为控制变量,分别得到终端时刻固定和可变两种情况下的最优控制模型,并采用高斯伪谱法对最优控制问题进行求解,以得到最优攻击策略。最后,对敌方杀伤力未知时我方无人机的攻击策略进行分析,同样可以得到相应的最优攻击策略。在给定的初始条件下进行了一系列仿真验证,仿真结果表明了模型的合理性和算法的有效性,所述方法可以为相应的空战决策提供依据。

The suicide drones' attack strategy under the influence of enemy's escort free-flight decoys is considered. Firstly, according to the suicide drone's operational characteristic, improved Lanchester equations are proposed. On the basis of airborne sensor's operational performance analysis, differential equations of the both sides' force attritions are established, so that the suicide drone's warfare rule can be described. Secondly, the optimal control method is applied to attack strategy analysis in Lanchester equations. Considering the Lanchester equations as state equations and taking suicide drones' attack probability as the control variable, the optimal control models of fixed and variable at terminal time can be separately established. Both optimal control problems are solved with Gauss pseudospectral method, so that the optimal attack strategies can be obtained. Lastly, the suicide drones' attack strategied are analyzed when enemy's killability is unknown, and the corresponding optimal attack strategies can be obtained. Under the given initial conditions, a series of simulations and verifications are carried out. The simulation results show that the models are feasible and the algorithm is effective, the methods described in the paper can provide references for air combat decision making.
