% planar_dolpcheby.m - Dolph-Chebyshev Weights for Planar Arrays
%
% Example: [w] = planar_dolphcheby(dx dy N M RdB)
%
% Inputs:
% dx = element spacing in units of lambda in x direction
% dy = element spacing in units of lambda in y direction
% N = number of array elements in x Direction
% M = number of array elements in y Direction
% R = relative sidelobe level in dB
%
% Output:
% W = matrix of array weights
function [w] = my_planar_dolphcheby(dxdyNMRdB)
R = 10^(RdB/20);
x0 = cosh(1/(N-1)*acosh(R));
Bpsi=zeros(NM);
% Finding Bpsi(PSIxPSIy) using Chebyshev Polyniomials
for l1 = 0:N-1
for l2 = 0:M-1
PSIxl1 = (l1-(N-1)/2)*2*pi/N;
PSIxl2 = (l2-(M-1)/2)*2*pi/M;
x = x0*cos(PSIxl1/2)*cos(PSIxl2/2);
T0 = 1;
T1 = x;
