AWR1642: DPIF_DetMatrix data format

Daniel Cheng1

Part Number: AWR1642
Other Parts Discussed in Thread: AWRL6432,

Hi Expert,

I am currently trying to retrieve the data after running Capon2D. Based on the example, the data is stored in detMatrix->data. According to the DPIF_DetMatrix Struct Reference, it only defines one format and arrangement. However, in the example, a custom format (format 2) is used without specifying the arrangement.

Is there any way to know the exact data layout? For instance, something like: uint16_t x[azimuthFftSize][elevationFftSize][numRangeBins].
Additionally, for Capon1D, is the data also stored in detMatrix? If so, what are the differences in the arrangement compared to Capon2D?

Any clarification or documentation on this would be greatly appreciated.

Daniel

Hi Daniel,

Sorry for the delay. Can you clarify which toolbox example and SDK are you trying to run?

Hi Shailesh,

Thanks for getting back to us. The SDK I’m using is MMWAVE_L_SDK_05_05_02_00, and the example I tried to run is:
radar_toolbox_3_20_00_04 / Automotive_InCabin_Security_and_Safety / AWRL6432_Life_Presence_Detection_Demo_Capon2D.

Just to clarify: when I initially reached out to Daniel, I had downloaded the example intended for AWR1642, so the post was tagged accordingly. However, I later switched to AWRL6432. I didn’t mention this change earlier, so please note that the actual platform is AWRL6432.

Daniel initially posted this question on my behalf, but I thought it would be more efficient to reply directly so you have the details needed to proceed. Please let me know if you need any additional information or if this difference impacts compatibility.

Regards,
Maureen
