Hi,

Welcome to the E2E forums!

peakVal here is the SNR of the detected peak on a logarithmic scale (decibels). This SNR comes from CFAR processing: It is the ratio of the peak value (cell under test) and the average value of the surrounding noise cells.

Have a look at the code documentation and source of the functions: cfarCa_SO_dBwrap_withSNR, cfarCadB_SO_withSNR.
