Hello,
I am struggling to understand how I can convert a linear array code to a 2D by changing or adding some lines of code.Here is what I have got so far:
%Parameters
Fc=1255e6; %/Hz Carrier frequency
C=3e8;%/m/s Speed of light
Lambda=C/Fc;%/m Wavelength
ESepx=0.49*Lambda; %/m Element separation in the x direction
ESepz=0.49*Lambda;%/m Element separation in the z direction
Nx=4; % Number of Elements in the x direction
Nz=16;%Number of Elements in the z direction
% First lets define a planar array in 3D space
Elementpos=zeros(Nx,Nz);
Elementpos(1,:)=(-(Nx-1)/2:(Nx-1)/2)*ESepx;
Elementpos(:,1)=(-(Nz-1)/2:(Nz-1)/2)*ESepz;
figure(1)
plot(Elementpos(1,:), Elementpos(:,1), 'x')
xlabel('x axis (m)');
ylabel('z axis (m)');
title('element position');

Meant to put this as an answer, not a comment.
