摘　　要：给出了一种在不确定环境下的无人机攻击决策分析方法。首先分析机载雷达的作战性能,得到正确判别敌方目标和错误判别敌方目标二者之间的关系;然后建立了一种基于Lanchester方程的诱饵弹干扰下的无人机攻击决策模型,进而表示出目标识别准确度对作战进程的影响;随后通过对Lanchester方程积分,得到了真目标损耗和假目标损耗二者之间的函数关系,从而完成对Lanchester方程的化简;最后采用差分进化算法来进行无人机的攻击决策优化,并且通过作战仿真验证了该方法的有效性。The analytical method for UAVs＇ attack decision on the uncertain condition is presented. Firstly, the airborne radar＇ s operational capability is analyzed, thus the relationship between correctly and incorrectly recognization of enemy targets can be indicated. Secondly, UAVs＇ attack decision in the decoys jamming scenario is modeled based on the Lanchester equations, and then the effects of target rec- ognition accuracy on combat process can be expressed. Thirdly, In order to obtain the function relation- ship between true targets attrition and false target attrition, the Lanchester equations are integrated and simplified. Lastly, the differential evolution algorithm is applied to UAVs＇ air-combat decision-making As is illustrated, the simulation shows that this model is effective.
