Hi TecnicakSupport
I would like to know how to calcurate "Range(meters)".
It's is horizontal axis of graph "Range Profile for zero Doppler" of mmWave Demo Visualizer.
For example,
----------------------------------------------------------------------------------------------------------------
numAdcSamples = 128 [sample]
digOutSampleRate = 5300 [ksps]
freqSlopeConst = 100 [MHz/μs]
"ADC sampling time" = numAdcSamples / (digOutSampleRate * 1000) = 24 [μs]
"ADC band" = freqSlopeConst * "ADC sampling time" = 2.4 [GHz]
"Range Resolution" = c / (2 * "ADC band") = 6.2 [cm]
----------------------------------------------------------------------------------------------------------------
In this case, is it correct that the distance per sample is 6.2 cm?
So, I think the maximum distance on the display is "Range Resolution" * numAdcSamples = 7.9 [m]
Best Regards
