chebyweight.m

由切比雪夫权值矢量及阵元间距画波束方向图：有x输入

function weight=chebyweight(sensor,mainbeam,sidelevel,dspace)
%chebyshev weight
%chebyweight(sensor,mainbeam,sidelevel,dspace)
[m n]=size(mainbeam);
mainbeam=reshape(mainbeam,m*n,1);
%普通chebyshev加权
sidelevel=abs(sidelevel);%%%%%%%%%%
w1=chebwin(sensor,sidelevel)';
%w1=ones(1,sensor);
dphase=-2*pi*dspace*repmat(sin(mainbeam*pi/180),1,sensor).*repmat((0:sensor-1),m*n,1)
weight=repmat(w1,m*n,1).*exp(j*dphase);

weight=normalizebeam(weight);
