Hi,
I would like to steer the beam pattern of a ULA so its at -25° and 25°.
My code is shown below:
c = 3e8;
fc = 2e9;
lambda = c/fc;
NoOfTxAntenna = 4;
txarray = phased.ULA('NumElements',NoOfTxAntenna,'ElementSpacing',lambda/2);
steer_ang = [25;0];
stv = phased.SteeringVector('SensorArray',txarray);
w = stv(fc,steer_ang);
figure,
pattern(txarray,fc,[-180:180],0,...
'PropagationSpeed',c,...
'CoordinateSystem','polar',...
'Type','powerdb', ...
'Weights',w)
Currently the beam pattern is as shown below.
Many thanks
