MMIC Radar Power Received Level

Question asked by c.alistarh on Feb 21, 2018

Hi,

 

We are using the custom software provided by AD for the ADAR7251, and would like to know which units are exactly in this plot:

It appears as dB, but I guess this should be unnormalized power levels (maybe dBm?)

 

Also, the exported data in .csv format, is a 16384x4 matrix, being the rows the FFT Size and the each column the data from each receiver. This data seems to be the time domain signal, as presented below:

But in order to be able to process the received power level, what's the amplitude scale? Maybe microVolts?

Hope you can give me a hand on this.

 

Many thanks,

Pascual
