Hi team,

SDK: mmwave_sdk_02_00_00_04

Application: mmwave_industrial_toolbox_2_4_0/lab0012_srr_16xx:

Question:

We want to do compRangeBiasAndRxChanPhase like mmw application.

And there is a define "COMPENSATE_FOR_GAIN_PHASE_OFFSET" in dss_data_path.c of SRR application.

If we want to do compRangeBias calibration like mmw demo application, how to implement it in SRR application?

Thanks

Hello John,

The SRR demo does not implement the range bias compensation.
Without the calibration, there is ~8cm offset bias in the range measurements. For the SRR demo, this level of absolute accuracy was not a requirement.

To implement it for your application, I would suggest that you refer to the implementation in the 16xx OOB demo and then add it into the SRR demo.
Some key things to note:
- The bias correction occurs in the MmwDemo_XYcalc function of the dss_data_path.c (refer to line 645 in the OOB dss_data_path.c). You would need to implement similar logic in the MmwDemo_XYcalc function for SRR
- Because the SRR demo does not utilize CLI commands for configuration you will need to handle the calibration command as consts similar to how the profileCfg command is handled as srr_config_chirp_design_*

Hi Amanda,

Thanks for your help.

I will check the OOB demo source code.

If we have any question, we will create new thread.

Thanks

John
