Questions about the calculation of X, Y and Z coordinates

Other Parts Discussed in Thread: AWR1843

Hi,

I have looked at the modules that show how to estimate the distance, speed and angle.. in an FMCW radar (AWR1843) and it is clear. But I didn't find how we can estimate the coordinates X,Y and Z of an object detected.

So I want to know how X,Y and Z is calculated ??

X,Y are computed based on sin(theta) information

Please see

Data Path (X,Y)

Thank you

Hi Cesar,

Thank you for your answer. I think from the sensor geometry shown below we can estimate X, Y and Z where R= Range and Phi= phase % at the Zaxis.

Yes, the snapshot you shared is part of the mmWave SDK documentation
