Hi every one
I would like to do a phase antennas calibration of AWR1443 using a reflector corner placed in the front of the radar.
After calibration, I visualize the phase of each antenna according the azimuth of the corner reflector.
Azimuth = 0
So, lets say that the error is marginal (equiphase front)
Azimuth = 20 degree
I noticed a specific pattern within each 4 antennas when I translate a corner in the right side of the radar. Theoretically, we expect a linear phase variation (attached file).
How we can explain this different in the phase across the antennas?
Thank you
