9524 仿真结果表明,航空集群各节点均能够形成一定的反隐身探测能力,不同集群构型能够适应不同威胁等级的反隐身任务需求; ‭The simulation results show that air cluster nodes are able to form a certain amount of stealth detection ability, able to adapt to different cluster configuration different threat level against stealth mission requirements;
9525 ‭发射节点通过S形机动能够达成良好的雷达补盲效果。 ‭Launch node through s-shaped motor can achieve a good radar blind effect.
9526 在广义数据包络分析方法(data envelopment analysis,DEA)有效性度量方面还存在以下两个问题有待解决:第一,当广义DEA模型无可行解时,尽管被评价单元本身是有效的,但却无法用具体数值刻画其有效程度; In the general method of data envelopment analysis (data envelopment analysis, DEA) effectiveness measures aspect also has the following two problems to be solved: first, when general DEA model is line solution, despite being evaluation unit itself is effective, but it cannot use specific numerical depicting its effective degree;
9527 第二,当单元为广义DEA有效时,某些单元的效率值存在被高估的情况。 Second, when the unit is generalized DEA effective, efficiency values of some units are overvalued.
9528 为解决这些问题,首先给出一个拓展的广义DEA模型。 To solve these problems, first of all gives a generalized DEA model.
9529 然后,给出了一种判定广义DEA模型存在无可行解情况的充要条件,以及单元效率被高估的判定条件。 Then, presents a judgement of generalized DEA model has no line solution is necessary and sufficient conditions, and the unit efficiency overvalued decision condition.
9530 同时给出测定单元效率的3种方法,并讨论这些方法与原有测定方法的关系。 At the same time gives three kinds of method for determination of unit efficiency, and discuss the relationship between these methods and the original measuring method.
9531 最后,通过实际例子进行了对比研究。 Finally, a practical example has carried on the comparative study.
9532 在高频、远场条件下,对海上多角反射体构成的无源对抗系统的雷达散射面积(radar cross section,RCS)进行预估。 Under the condition of high frequency, the far field, the sea of corner reflector more passive countermeasure system of radar scattering area (radar cross section, the RCS) carries on the forecast.
9533 针对传统算法计算量大、复杂度高的问题,提出综合利用改进的几何光学/区域投影法(geometrical optics/area projection,GO/AP)和散射中心合成法,进行海上角反射体群RCS的快速预估。 ‭For large amount of calculation, the problem of high complexity of the traditional algorithm, put forward the comprehensive utilization of improved geometrical optics/area projection method (geometrical called/area of the projection, the GO/AP) synthesis and scattering center, sea Angle reflector group of RCS rapid estimates.
