Hello! How does the use of Phased Array System Toolbox to calculate the ratio of the simulated directional antenna array?

Hi Pomisov, could you clarify what you mean by ratio?

Hi Pomisov,
There are two ways you can see the directivity information.
The first one is to plot the radiation pattern. For example
fc = 3e8; c = 3e8;
h = phased.ULA(4,0.5);
plotResponse(h,fc,c,'format','polar')
You can also use ArrayGain. It is the SNR gain achieved by the array compared to a single element. It is not exactly the directivity but it is related to that.
fc = 3e8; c = 3e8;
h = phased.ULA(4,0.5);
hag = phased.ArrayGain('SensorArray',h,'PropagationSpeed',c);
% calculate array gain at boresight in dB
g = step(hag,fc,[0;0])
HTH,

Does the code above using ArrayGain works for you? If not, could you give me a simplified example? Thanks.
