IWR6843ISK: Increasing distance

Part Number: IWR6843ISK

Hello!

We took the recommendations from the previous thread and got improvements.

We have additional questions:

Does TI have a traffic monitoring firmware that emits three TX channels to achieve maximum range?
Is there technical documentation for firmware 68xx_traffic_monitoring_70m_MIMO_2D?
In our experiments, we use firmware BSS - xwr68xx_radarss.bin and MSS - xwr68xx_masterss.bin, with standard default settings, we get an unambiguous speed measurement in a small range of +-7 m/s. Does TI have firmware for measuring speeds +-50 m/s?
To increase the range of the radar, TI recommended that we use an antenna lens, or similar device. Does TI have reference drawings for this device. Or the part number of the device available for purchase?
If we manage to increase the range of the radar, with what firmware and settings will we be able to see the original signals and process them in TMC?

Thank you.

No, but you can refer to the example in C:\ti\radar_toolbox_1_10_00_13\radar_toolbox_1_10_00_13\source\ti\examples\ADAS\mrr_beamsteering\ for similar work that you can use to guide yourself though this.

what toolbox are you referring to here? Usually there should be a docs folder in these projects.

You can create this using the mmwave sensing estimator tool here. See the advanced chirp design tab in the tool.

TI does not product antenna lenses. You are free to use any lens, and I'd recommend evaluating their spec sheets to determine that they work well for 60 GHz.

I don't know what TMC stands for in this context. Can you explain your request please?
