Hi,
I was confirming the maximum velocity and velocity resolution values that the oob demo gui reports. I am confused for the values reported for the 4rx/2tx and 4rx/1tx cases. The expressions I believe for these values are
Maximum velocity = wl/4/t_c
Velocity resolution = wl/2/t_f
where
wl is the wavelength ~.3/77 = .003896 meters
t_c chirp cycle time .973 ms
t_f chirp frame time t_c*32 for the 4rx/2tx case and t_c*16 for the 4rx/2tx case
configuration parameters for the two cases are
4rx/2tx
channelCfg 15 5 0
profileCfg 0 77 429 7 57.14 0 0 70 1 240 4884 0 0 30
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 4
frameCfg 0 1 16 0 100 1 0
4rx/1tx
channelCfg 15 1 0
profileCfg 0 77 429 7 57.14 0 0 70 1 240 4884 0 0 30
chirpCfg 0 0 0 0 0 0 0 1
frameCfg 0 0 16 0 100 1 0
Using this information, I get
4rx/2tx 4rx/1tx
Maximum velocity (m/s) 1 1
Velocity resolution (m/s) .0625 .125
Chirps per frame 32 16 (obtained from dataPathObj->numChirpsPerFrame)
The gui provides the values in the attached images.
Can you please explain the discrepancy? Thank you.
