Correlation coefficient between two antennas in array
Plot Correlation of 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 Array
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 0.1417 0.1123 0.0826 0.0524 0.0215 0.0102 0.0429 0.0763 0.1094 0.1409 ⋮
