CCS/IWR6843: IWR6843 3 Antennas for Azimuth detection.

Tool/software: Code Composer Studio

Hi experts,

Based on IWR6843 ES1.0 we have designed a new board which has 3 antennas in the azimuth . It works well with the lab0012_srr_16xx demo that we have modified.

here is my question :

How to modify the code to enable Tx1、Tx2、Tx3 in TDMA model because we want to inprove the angle resolution.

Could you give us some advice?

Thank you !

Hi Simon,

I've asked an expert to look into this and we should have an answer for you later this week.

Simon,

You can take a look at the MRR demo found in the automotive toolbox here: http://dev.ti.com/tirex/explore/node?node=AObIl5yAPR-DjIwxgdgyuA__AocYeEd__LATEST

This lab enables all three TX antennas. It was developed on the AWR1843.

Thanks Kyle ,

I realized that this lab enables 2 tx for azimuth and tx for elevation in USRR model. Is that means I only need to change the receive channel data path flow and chirp tx sequence ?

what should I do ?

Simon

Simon,

That approach sounds like it would work. You can also try the MRR demo on your custom board and see if it works as is.

You can also use the E2E thread as a guide for migrating your code: https://e2e.ti.com/support/sensors/f/1023/t/841169?IWR6843-Placeholder-Migration-Guide
