IWR1443: Custom TX antenna placement

ASM3

Part Number: IWR1443
Other Parts Discussed in Thread: IWR6843ISK

Hello,

I am working on an implementation of a 3D application (Az, El, Range) by using the IWR1443 chip and the mmWave SDK (2.1.0.04). For this purpose I have designed a specific antenna configuration setup, by placing the Tx antennas (Tx1, Tx2, Tx3) in the elevation plane for gaining elevation angular resolution enhancement. How can I generate a software input for the specific antennas geometry (virtual Rx geometry), or is this input generated during calibration procedure?

Thanks,

Hello,

The software will depend on your antenna design. Can you please send me your antenna placement diagram?

Also, please read the MIMO Radar App Note for help on radar calculations.

Thanks,

Chloe

Dear Chloe

Thanks for your reply.

Please find enclosed the antenna placement (Tx -red, Rx - blue).

Best,

Hello,

Please take a look at this app note for more information on radar calculations with reference to the locations of the antennas.

Dear Chloe,

Thanks for your reply and the application note.

Nevertheless, I still wonder regarding the required software modification of the demo code (using SDK 2.1.0.04) in case of a custom 3D antenna geometry design as described in my previous posts e.g.

Thanks and regards,

Hello,

Please compare the IWR6843ISK and IWR6843ODS demo codes for examples on how to change software according to antenna placement.
