Hello,
I use the AWR1843 radar with the OOB demo. I configured it with the following config:
const char Config[1000]=" sensorStop \
flushCfg \
dfeDataOutputMode 1 \
channelCfg 15 7 0 \

I fix the radar on a moving car and start moving at a speed of 10km/h to 54km/h and I save the detected data (x,y,z,velocity).
My problem is that when I check the data, I don't see a speed greater than 2.61 or -2.61 (9km/h). I don't see a speed higher than 2.61 or -2.61 (9km/h) when I moved at a speed of 20 30 40 54km/h
I want to know if there's any filtering happened in velocity ? or if the the problem is in the configuration of the chirp of the radar.. ??
PS: I'm disabling staticclutterremoval. and cfarFovCfg -1 1 -15.37 15.37 => the maximum velocity is 54km/h
Best,
