Correlation coefficient between two antennas in array
Plot the correlation between 1 and 2 antenna elements in a default linear array over a frequency range of 50MHz to 100MHz.
h = linearArray; correlation (h,50e6:1e6:100e6,1,2);
Calculate correlation coefficient of default rectangular array at a frequency range of 50MHz to 100MHz.
h = rectangularArray; rho = correlation (h, 50e6:1e6:100e6, 1, 2)
rho = 51×1 0.1406 0.1110 0.0812 0.0510 0.0200 0.0119 0.0448 0.0782 0.1114 0.1427 ⋮
