I'm looking to simulate the effect of introducing phase error to elements of a phased array antenna and the impact on the beam pattern formed. I'd like to introduce random phase errors on each of the channels and then extract key parameters such as the peak gain, bandwidth and sidelobe levels.
fc=1e9;
c=3e8;
lambda=c/fc;
array = phased.URA('Size',[4,4],'ElementSpacing',[lambda/2,lambda/2]);
pattern(array,fc,-90:90,-90:90);

You can do somethign like this to simulate a phase error uniformly distributed within +/- 2.5 degrees in each element.
pherr_deg = 5*rand(getNumElements(array),1)-2.5;
pattern(array,fc,-90:90,-90:90,'Weights',exp(1i*deg2rad(pherr_deg)));
