There is a question is about the mmWaveSensingEstimator on ti.com and its precision (tolerance consideration).
Following quotation for SNR calculation has been found in our training material.
https://training.ti.com/sites/default/files/docs/mmwaveSensing-FMCW-offlineviewing_0.pdf
It’s about calculationg the maximum measurement time T_meas which depends of the number of chirps and chrip duration.
Furtheremore it’s obvious by the code of mmWaveSensingEstimator that the number of virtual antennas (num_virtual_rx) is considered.
For calculations of different systems we used a custom tool which uses instead of the measured time T_meas the system bandwith for SNR calculation.
Furhtermore we cosidered quantization of the ADC and the process gain of signal processing.
It’s clear that the mmWaveSensingEstimator is “ just” a estimator for a rough estimation.
Neverthless, I like to understand why TI is using the SNR quotaion with T_meas.
Can you elaborate a bit more on the background and the tolerances we have experienced by this quotation.
