Hi everyone:
I am a student who is studying the AOA detection by MUSIC.And I follow the website (https://decibel.ni.com/content/docs/DOC-25716) to do.
However,the perfomance is not same at different true angle.
Can somebody tell me what is the probable problem ?
I think that it is cause by the hardware such as antenna.
I used the simulation code to run MUSIC algorithm, finding one thing is the amplitude sqrt(I^2+Q^2) always a constant.
L=1000;
T=0:1/ fs : ( L - 1 ) / fs;
w=2*pi*100e3;
xx=2*exp(1i*(w*T));
xx is the original I simulate.
HOWEVER, the experiment result is not a constant and some of them seem to be periodic function...some are not..
I think I should focus on the A(t) and thita(t) in I/Q data, however, this program focus on thita(t) and In-phase data.
This confused me because I do not know what is the matter I need to check and I do not know where is the truth.
