AWR1243: A question about AWR1243's work mode in the cascaded imaging radar system

Part Number: AWR1243

Hello TI team:

I want to know the cascaded imaging radar system whether support TDM-MIMO and BPM-MIMO.

If it can use TDM-MIMO,how to make one antenna of one chirp transmites frame and the remained antennas of other chirp recieve frame at the same time?

How to control the one chirp transmites and recieves and other chirp only recieves?

Hi,

The cascade imaging radar system supports TDM MIMO.

The TX can be enabled separately through SW configuration.

thank you

Thanks for your reply.

But I can't find the description about chirp being enabled separately.

In my opinion, in the TDM MIMO, only one TX antenna is enabled,and other TX antennas are disabled. So, there must be one chirp have one enabled TX antenna and four RX enabled antenna, the other chirp only have four enabled RX antenna.

How do I set the API to implement the situation? Which the API could controul the chirp only recieve not transmites?

Hi user5834494,

I think the question you can be answered by reviewing the AWR Interface Control Document (ICD) which is included with the DFP package here: http://software-dl.ti.com/ra-processors/esd/MMWAVE-DFP/latest/exports/mmWave-Radar-Interface-Control.pdf.Please check out the "5.5.2 Sub block 0x0101 – AWR CHIRP CONF SET SB".

I also recommend you review the AWR Chirp Programming Guide here: http://www.ti.com/lit/an/swra553/swra553.pdf

Thank you,

-Randy
