Other Parts Discussed in Thread: IWRL6432
HI,
I noticed that if I want a vel res with 64 chirps in BPM mode, I need to configure the numOfChirpsInBurst to 128, which has explained in ' Parameter Tuning and Customization Guide for the IWRL6432 Motion/Presence Detection Demo.pdf ', page 40
Here is my wave confuration, respectively in mmWave sensing estimator and sdk
mmWave sensing estimator:
chirpComnCfg 8 0 0 256 4 30 0
chirpTimingCfg 6 0 0 15 76
channelCfg 7 3 0
frameCfg 128 0 4800 1 100 0
ccs sdk:
When debugging the sdk, the calculated doppler step is 0.43.
When using the sensing estimator, the vel resolution is 0.214
I'm not sure where I made a mistake, is the problem that sdk doesn't consider the fftshift, both positive and negative vel?
Which vel res should I use?
