how to get plot spectrum for this function of DOA?

fs = 8000; t = (0:1/fs:1).';
x1 = cos(2*pi*t*300); x2 = cos(2*pi*t*400);
ha = phased.ULA('NumElements',10,'ElementSpacing',1);
ha.Element.FrequencyRange = [100e6 300e6];
fc = 150e6;
x = collectPlaneWave(ha,[x1 x2],[10 20;45 60]',fc);
rng default;
noise = 0.1/sqrt(2)*(randn(size(x))+1i*randn(size(x)));
hdoa = phased.ESPRITEstimator('SensorArray',ha,...
    'OperatingFrequency',fc);
doas = step(hdoa,x+noise);
az = broadside2az(sort(doas),[20 60])

Hi Ali,

Unlike beamscan or MVDR, ESPRIT is not a spectrum based algorithm. So the result of the algorithm is the angle itself. do you have anything specific you are looking for?

So if we need to draw the power-angle curve using the espritestimator, is there any way to make it?
