摘　　要：针对大中型察打一体无人机(Reconnaissance and Strike Integrated Unmanned Aerial Vehicle,RSUAV)在中空环境抗打击能力弱、生存能力差的问题,本文研究一种箔条弹掩护的质心干扰策略。该策略以导弹与RSUAV的最近距离为评估指标,旨在延长RSUAV在对方导弹威胁下的存活时间,进而提高其在执行任务过程中的生存概率。本文首先详细构建RSUAV、箔条云和导弹的运动模型,深入分析箔条云成型过程,详细探讨箔条弹在投放与实际发射时速度的差异性,并考虑多个箔条云同时存在的质心运动模型,结合箔条弹投放有关参数形成质心干扰的约束条件和间隔时间,最后,在质心干扰结束时,通过RSUAV逃离指标判断RSUAV是否成功逃脱。仿真结果表明,在给定初始距离和逃脱时间条件下,对方导弹和RSUAV的最近距离增大至导弹爆炸范围的127倍以上,RSUAV存活时间延长约62.5%,可见本文提出方法能够帮助RSUAV提高生存概率,在导弹、箔条弹和环境条件参数变化时仍然具有有效性和健壮性。To address the issue of weak anti-strike capability and poor survival capability for medium and large-sized reconnaissance and strike integrated unmanned aerial vehicles(RSUAVs)in medium-altitude environments,this paper investigates a centroid jamming strategy for RSUAVs protected by chaff cartridges.The strategy uses the closest distance between the missile and the RSUAV as an evaluation index,aiming to extend the survival time of RSUAVs under missile threats and thus to improve the survival probability of RSUAVs during mission execution.Firstly,detailed motion models of RSUAV,chaff cloud,and missile are constructed,the forming processing of chaff cloud is deeply analyzed,and the velocity difference between the chaff cartridge deployment and actual launch is explored in detail.Considering the centroid motion model of multiple chaff clouds coexisting simultaneously,combining relevant parameters of chaff cartridge deployment,centroid jamming constraint conditions and interval times are formed.Finally,at the end of the centroid jamming,the RSUAV escape indicator is used to determine whether the RSUAV has successfully escaped.The simulation results demonstrate that under the given initial distance and escape time conditions,the closest distance between the missile and the RSUAV increases to more than 127 times of the missile explosion range,and prolongs the survival time of the RSUAV by about 62.5%.The proposed method can help to improve the survival probability of RSUAV,and it presents the effectiveness and robustness with the parameters variations of missile,chaff cartridge,and environmental conditions.
