Part Number: AWR1642BOOST

Hi experts,

Q1:Why is the Profile Id is just in the range 0 to 3?

Q2:Why is the Start/End Chirp is just in the range 0 to 511?

Thanks in advance!

Hello NanShan ,

With the existing profile and chirp(start/end) indices ranges it is possible to have all the all known chirp configurations for MIMO radar.
Hence we have the defined ranges for profile Id and chirp index.

Thanks,
Raghu

Hi Raghu，

Thanks for your replies!

We are random to use these profile and chirps?
ex：first 100 chirps we choose profile 0，then second 100 we choose profile 1 ?

Best regards!

Hi NanShan,

Yes you can use different set of chirps and associate different profiles .

You can define array of chirp configuration (AR_CHIRP_CONF_SET_SB) such that :
chirp_config[0] sets the "PROFILE_INDX =0" and "CHIRP_START_INDX = 0" and "CHIRP_END_INDX = 100"
chirp_config[1] sets the "PROFILE_INDX =1" and "CHIRP_START_INDX = 101" and "CHIRP_END_INDX = 200"
...

Regards,
Raghu
