AWR1443BOOST: Detected Object(a metal plate) is directly above AWR1443 , but X-Y Scatter Plot in mmWave DEMO Visualizer seems 67 degree(not 0 or 90) . What X,Y means? What is the coordinate?

Detected Object(a metal plate) is directly above AWR1443:

X-Y Scatter Plot in mmWave DEMO Visualizer:

I read X Y from the plot and calculate atan=ATAN(I17/H17)*180/PI():

Why the angle is not 0 or 90?

What is the coordinate,X,Y 's meaning?

Thanks a lot!

Hi Mars,

If you are observing a shift in the angle of arrival with a stationary corner reflector kept at known distance (0 degrees), it could be that you would have to perform calibration on your sensor (steps are mentioned in the SDK userguide). Please do give this a try and let me know.

Thanks for your answer. But it is not the real reason. The reason is that the metal plate were incline. After I adjust the metal plate, the measurement is almost 90 degree.
