AWR1843: How to understand the intensity of range FFT?

Part Number: AWR1843

When plotting the range FFT, I know each peak corresponds to the object at a particular distance. But how to understand the intensity on 'y-axis'? Is it determined by reflecting objects and affected by signal absorption, diffraction etc.?

Hi,

Yes the received signal is affected by all the factors you mentioned.

There have been many threads related to the units of the range FFT output.

It is important to understand that these values do not have absolute units.

Only relative value matters.

Thank you
