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 0.1414 0.1120 0.0822 0.0520 0.0212 0.0106 0.0433 0.0767 0.1098 0.1412 ⋮
