close all clear all clc m = input('enter the number of elements = '); d = input('direction = '); signal=(sin(d* pi/180)); ad = exp (-1j * pi [0: m-1]'*signal); thetas = [-90:.1:90]; tm = thetas * pi/180; am = exp (-1j * pi * [0: m-1]' (sin (tm))); A = abs (ad'* am); A = A / max (A); figure, polar (tm, A) A = 10*log10 (A); figure, plot (thetas, A); xlabel ('angle[degrees]'); ylabel ('Normalized Beam Power[dB]'); grid on
