Abstract : according to the probability model of aerointerceptor ' s interception effect under optimum target distribution form ( tdf ) , the optimum tdf in which aerointerceptors intercept groups of attack - planes are deduced , the relation among dispatching fighter number , airport ' s tactical and technological parameters , aerointerceptor ' s tactical and technological parameters , and attack - situation of attack - planes is researched , the quantitacation relationship are then determined which should satisfy when airport ' s aerointerceptors conduct optimum target distribution on groups of attack - planes . starting from operational practice , the model can provide certain theoretical basis for the military decisions 文摘:根据截击机在优化的目标分配形式下拦截效果的概率模型，导出了截击机在拦截多攻击机机群时的最优目标分配形式;研究了机场飞机起飞架数与机场战术、技术参数、机场飞机的战术、技术参数以及与攻击机的进攻态势之间的关系;确定了多机场飞机对多攻击机机群进行最优目标分配时所应满足的量化关系，给出的模型可对作战决策过程提供理论依据。
Fourthly , we discuss and simulate the transformation method of relative parameters of ground target based on data link . and then we analyze decision algorithm of air - to - ground attack . especially , we educe three dimensional terminal guidance law of air - to - ground missile in the disturbance of wind , and give the simulation result 本文也研究了空对地攻击的若干技术,包括对获得数据链指挥下地面目标相对于某攻击机当前时刻相关参数的方法进行了阐述及仿真,并在此基础上讨论了单机对地面多个目标的攻击决策算法,同时提出了一种风干扰下空地导弹的三维末制导导引律,且利用数字仿真进行了验证,并指出研究空地导弹导引律时考虑风影响的必要性。
To overcome the shortages of the traditional proportional guidance in attacking maneuvering targets , the paper firstly established the relative motion models for the anti - ship missile and the target in three dimensions , then based on the optimal guidance law for aiming at non maneuvering targets and the sliding - mode control theory , the optimal sliding - mode guidance law in three dimensions , which was more easily - accomplished in engineering , was derived by making the pitch plane and yaw plane superposition 摘要针对传统比例导引法攻击机动目标的不足，建立了三维空间中反舰导弹和目标的相对运动模型，在研究反舰导弹攻击非机动目标的最优制导律基础上，利用俯仰和偏航两个平面相叠加的方法，结合滑模控制理论设计了工程上易于实现的三维模型下的反舰导弹最优滑模制导律。
In the french air force , mirage 2000 fighters in operation are : mirage 2000c / b single seater and two seater for air defence ; mirage 2000n , two seater , designed for all weather nuclear penetration at low altitude and very high speed ; and mirage 2000d , which is an upgraded version of the mirage 2000n , for automated bombing using conventional and laser guided munitions ; e type for multi purpose exporting version ; r for single seat day / night eaporting version 在法国空军内，现役的幻影2000战斗机为幻影2000c型单座战斗机、 b型双座战斗教练机、幻影2000n双座全天候低空高速核攻击机以及其改进型d型常规精确制导武器攻击机、幻影2000e多任务出口型、幻影2000r单座昼夜侦察出口型。
We studied the on principle of drm ' s " merge " , which is very useful in future war , and propose that missile ' s " merge " is a new field of ots ( over the shoulder ) research because target is after the aircraft when it is missed by missile 本文主要研究了在未来空战中将发挥十分重要作用的擦肩发射的原理，认为擦肩发射是越肩发射的一种新形式，它可以通过缩短导弹的最小发射距离来增大本机的攻击机会，在近距格斗中由于擦肩发射放宽对本机指向的要求，从而降低了对本机敏捷性的要求。
In this paper , the mechanism , methods of and countermeasures to denial of services attacks are discussed . after that , several packet marking schemes for traceback are reviewed and some improvements to the basic packet marking scheme are given , which reduce the workload and false positive rate in the attack tree reconstruction . knowing that in existing packet marking schemes , router marks packets with fixed probability , which results in that many packets are required in path reconstruction and that attacker could encumber path reconstruction via spoofed marking information 在本文中，我们首先研究了拒绝服务攻击的攻击机制、方法及其对策，并对以包标记的方式追踪拒绝服务攻击的来源的各种方法进行了深入的研究，分析了它们各自的优缺点，并对基本包标记方案作了改进，使得其攻击路径重构时的运算量和重构的误报率在原有基础上大为降低，达到或超过了其他一些方案的水平。
