Other Parts Discussed in Thread: AWR1843
Hi, I am trying to understand how the azimuth angle of targets is calculated. I have taken the raw data from the AWR1843 and am applying MATLAB's FFT to the range-doppler response across 8 channels:
angle_fft = fftshift(fft(rd_fft, N_bins));
I then am plotting the magnitude response and all looks great. My question is how do you map the FFT bins to actual angle values? I tried a linear relationship using:
angle_step = 180/N;
angles = linspace(-90, 90 - angle_step, N);
But this seemed wrong.
Any help in this area is greatly appreciated.
Many thanks.
