基于JPcap的ip数据包的分析，详细讲解了完成数据捕获分析的过程，其中包含了JPcap基本类的使用 (Based on the analysis JPcap ip packet detail on the completion of the analysis of the data capture process, which includes the use of the basic classes JPcap Analysis of IP data packet based on JPcap, explain in detail the process of data capture and analysis, including the use of JPcap basic class)

由于Kmeans聚类分析是一个局部的搜索过程，因此加入遗传算法进行全局搜索选择最优的初始中心点使得Kmeans算法产生较大的改进(Since Kmeans Cluster analysis is a local search process, so join a global search for the genetic algorithm to the optimal initial centers such Kmeans algorithm produces greater improvement)

fmincon finds a constrained minimum of a function of several variables. fmincon attempts to solve problems of the form: min F(X) subject to: A*X <= B, Aeq*X = Beq (linear constraints) X C(X) <= 0, Ceq(X) = 0 (nonlinear constraints) LB <= X <= UB (bounds)

假定半波长间隔均匀分布线列布阵的阵元数N=16，若入射平面波为f=62.5Hz的正弦信号，信号持续时间为0.4s， 系统采样频率 =1 KHz,阵列加权为均匀加权，分别给出 a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时，指向90度的波束形成器的输出序列； b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives: a) 90 degree response when incidence angles are: 0: 10: 100 degrees b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )

说明：  现代海战需要功能综合的作战平台和性能优良的 武器系统来应对，海战场复杂多维的环境因素对海上 兵力运用有很大的影响。因此，如何准确建立海战场 的评估指标体系并进行科学评判是指挥员做出决策的 重要前提。目前，海战场环境评估的方法有层次分析 法、模糊评判法、指数法等11’21。针对这些方法主观性 比较强等不足，本文引入云重心的评估方法简单易行， 科学有效，可操作性强。 基于云重心方法的海战场环境评估(Modern naval warfare needs integrated operational platforms and excellent weapon systems to cope with. The complex and multi-dimensional environmental factors of naval battlefield have a great impact on the use of naval forces. Therefore, how to accurately establish the evaluation index system of sea battlefield and make scientific evaluation is an important prerequisite for commanders to make decisions. At present, the methods of Marine Battlefield Environment Assessment include analytic hierarchy process, fuzzy evaluation, index method and so on. In view of these shortcomings, such as strong subjectivity, this paper introduces cloud gravity center evaluation method which is simple, scientific and effective, and operable. Sea Battlefield Environment Assessment Based on Cloud Barycenter Method)
