IWR1443BOOST: How to determine SNR of detected objects utilizing xWR1443 demo

IWR6843AOPEVM: Extract PeakVal or range intensity from SNR and noise plots in saved .dat file from Visualizer

Part Number: IWR6843AOPEVM

I'm running a IWR6843AOPEVM on the mmWave Demo Visualizer dev.ti.com/.../ and saving data files.

With the live demo, I can see both the Range profile (in dB) and the noise profile (in dB). When I parse the saved .dat file however I do not get anything like peakVal or range intensity. The 2 fields I get related any form of intensity are SNR and Noise. Is it possible to extract the Range Intensity or PeakVal from these 2 fields? Is so, what is the calculation to do so.

Am I missing something in the parser in that the .dat file saves the peakVal numbers or intensity numbers but I'm just not parsing them? If so, what should I insert into the parser and lookup library to extract those values. I have read the manual in the SDK for the Demo Visualizer but it hasn't been able to help me.

Thank you,

Peter
