IWRL6432: TX beamforming and RX beamforming

Part Number: IWRL6432
Other Parts Discussed in Thread: IWR6843

Tool/software:

Hi all

Would you mind if we ask IWRL6432?

Our customer considers developing MIMO radar using IWRL6432.
They are interested in IWRL6432.

<Question1>
Can it implement TX beamforming and RX beamforming using IRWL6432?
We assume that IRWL6432 only has two ports, it can't implement.
Should they use IWR6843?

<Question2>
Do you have any documentation which is relation to TX beamforming and RX beamforming?
We found followings, however it shows only TX beamforming.

Kind regards,

Hi,

I believe this is a duplicate thread of these.

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1394295/iwrl6432-about-beam-forming

RX beamforming is the way we estimate angle of arrival. We don't have specific documentation on it, but you could consult the AOA DPU documentation in the mmwave l sdk.

Best,

Nate

->OK, we got it. we are sorry to bother you, could you share us the AOA DPU documentation URL link?(We can't find it mmwave low power SDK.)

Just in case, if we deploy TX beamforming, three TX antennas need at least.
And documentation of TX beamforming are following.

Is our recognition correct?

Yes this is correct. IWRL6432 does not support TX beamforming

About AOA contents, there is only "DPU_AOA2DPROC_ERROR_CODE".
We can't find "api_guide_xwrL64xx" contents.
We are sorry to bother you, could you share the document?

Kind regards,
