clear clc
d=1 天线阵元的间距
lma=2 信号中心波长
q1=1*pi/4 q2=1*pi/3 q3=1*pi/6 q4=3*pi/4 四输入信号的方向
A1=[exp(-2*pi*j*d*[0:6]*cos(q1)/lma)] 求阵因子
A2=[exp(-2*pi*j*d*[0:6]*cos(q2)/lma)]
A3=[exp(-2*pi*j*d*[0:6]*cos(q3)/lma)]
A4=[exp(-2*pi*j*d*[0:6]*cos(q4)/lma)]
A=[A1,A2,A3,A4] 得出A矩阵
n=1:1900
v1=.015 四信号的频率
v2=.05
v3=.02
v4=.035
d=[1.3*cos(v1*n) 1*sin(v2(we)

利用熵值法判断某个指标的离散程度的。在信息论中,熵是对不确定性的一种度量。信息量越大,不确定性就越小,熵也就越小;信息量越小,不确定性越大,熵也越大。根据熵的特性,我们可以通过计算熵值来判断一个事件的随机性及无序程度,也可以用熵值来判断某个指标的离散程度,指标的离散程度越大,该指标对综合评价的影响越大。
因此,可根据各项指标的变异程度,利用信息熵这个工具,计算出各个指标的权重,为多指标综合评价提供依据。(Using entropy method to judge the degree of dispersion of a certain index.)
