TIDEP-0092: mmWave Studio show "Not enough chirps to perform 2D FFT" with SRR+USRR profile.

Part Number: TIDEP-0092

Hi team,

SDK version: mmwave_sdk_03_01_00_02

Studio version: mmwave_studio_01_00_00_00

Hardware: TIDEP-0092

Question:

We want to set SRR application profile like below and follow the attached file.

SRR: Fast chirp+Slow Chirp

USRR: 

The capture is successful and we could not display SRR data. 

The postproc always show "Not enough chirps to perform 2D FFT" in Subframe 1(SRR)

But we could display USRR frame. 

I attached our procedure that our TI FAE provides to us and attached the capture data for your reference.

Is anything we set wrong? 

Thanks.

    Weks,

    Please make sure that you also adjust the "Frame section" of the "SensorConfig" tab. If you do not make any changes to these values, you will not have enough chirps for 2D FFT processing. You will also not be implementing your chirps as intended.

    Regards,
    Kyle
