Hi,
I'm using NRF52811 to evaluate the direction finding. I have successfully got the phase data, but I found a strange thing:
I did some processing on phase data for easier analysis. I made the gap between all adjacent phases less than half the period so the curve will be continuous. And I used the linear regression line as the reference, and got the final curve as the above image shows. In theory, the phases of Antenna 3 should be on a straight line, but if it switch to Antenna 1 then switch back to Antenna 3, there will be a phase shifting for one full cycle ( In NRF the PI is 201, and the phase shift between two periods of Antenna 3 is 407, which is really close to 2 * PI ). So how can I analyze this kind of phase data?
Best regards,
Fan
