AWR1843BOOST: MRR Beam Steering Lab for MRR and USRR

Hang

Part Number: AWR1843BOOST

Hello,

Thanks for giving the MRR Beam Steering example for exploring more features of TI mmWave Radar.

I have two quick questions.

(1) Was the Beam Steering feature applied for both MRR frame and USRR frame? Because I only want to use the USRR frame for my application, like "#define SUBFRAME_CONF_USRR", in default, will be the Beam Steering applied to the USRR?

(2) Because I only use the USRR, I guess it will save some cycles from the MRR. I want to recalculate the frame duration of the USRR, how can I do it? In the default example, which includes both MRR and USRR, the frame duration was 60ms. If I only use USRR, how to measure the new frame duration?

Thank you very much for the help!

Best,

Hi,

(1) Beam Steering will apply only to USRR

(2) USRR sub-frame duration is defined in the configuration. It is 30ms

labs\lab0007_medium_range_radar\src\common\mrr_config_chirp_design_USRR30.h

#define SUBFRAME_USRR_PERIODICITY_VAL (6000000U) // 30ms

Thank you

Hi Cesar,

Thank you very much! That's really helpful. I have one more questions in labs\lab0011_mrr_beamsteering\src\common\mrr_config_chirp_design_USRR30.h

#define SUBFRAME_USRR_PERIODICITY_VAL (6500000U) // 32.5ms

In the mrr steering labs, it does not include the mrr_config_chirp_design_USRR50.h, in the mrr lab, it has. Can I add the mrr_config_chirp_design_USRR50.h to the mrr steering lab? Anything I should pay attention? Thank you very much!

Yes you can use that config.

Thank you

Hi Cesar,

Thank you very much, that's really helpful. I have one more question.

In the mrr steering lab, it doesn't include mrr_config_chirp_design_USRR50.h. However, in the mrr lab it has. Can I add the mrr_config_chirp_design_USRR50.h from the mrr lab to the mrr steering lab? Anything I should modify or pay attention?

Thank you for your help!

Best,

HI,

I noticed that there was a mistake in my first reply. The beam steering applies only to

MRR mode and not USRR.

Thank you

Cesar

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
