Hello everyone,
I am currently doing some measurements with IWR1443 + TSW1400. To evaluate the results I am using the Radar Studio PostProc tool as well as my own signal processing tool.
In my own tool I implemented a CFAR like described in HWA Part 2 manual ( http://www.ti.com/lit/ug/swru527a/swru527a.pdf ). So the CFAR calculates the noise (or noise + clutter) for each range-doppler cell.
Then I would think that you take the peak value of the angle FFT, because this value should correspond to the peak of the signal from your object. Now you can devide this peak value with the estimated noise(+clutter) value of the CFAR .
Unfortunately, my values are not equal to the SNR values estimated by PostProc tool.
Could you please provide any information of the way PostProc calculates the SNR (or tell me if my understanding above is correct)?
Thank you very much,
Enric
