IWR1843BOOST: Debugging Stationary Object Detection on IWR1843BOOST – Examples/Config for 50 m

Part Number: IWR1843BOOST
Other Parts Discussed in Thread: AWR2243

Tool/software:

Hi Team,

I am working with the IWR1843BOOST and need to enable stationary object detection within ~50 m.

With the existing examples (e.g., traffic monitoring), moving object detection works correctly, but stationary targets are not being retained in the output. I have already experimented with enabling/disabling and modifying static clutter removal (clutterRemoval), but this did not resolve the issue—stationary detections are still not visible.

To debug further, could you please clarify:

Are there any TI examples/demos where both stationary and moving objects are supported on the IWR1843BOOST?
Are there any reference configuration files/designs specifically tuned for retaining stationary targets up to 50 m?

Application context: Detecting vehicles that stop/park, pedestrians standing still, and obstacles on the road.

Hi,

Detecting stationary objects with radars is more challenging than detecting moving objects because the doppler information can't be used in the detection.

Detecting static pedestrians will not be possible with IWR1843BOOST.

You will need to consider a sensor that can transmit more power.

Thank you
Cesar

Thank you for the clarification.

Could you please specify which TI radar sensors validated for stationary object detection up to ~50 m?

A list of recommended sensors (or reference designs/demos) would be very helpful so we can evaluate the correct hardware platform for this application. If available, could you also share any benchmark results, documentation, or performance data that demonstrate stationary detection capability with those sensors?

Let me check with the team.

Thank you

Hi,

I discussed with extended team and we don't think we have a single chip solution that will be able to detect pedestrians in this configuration: static sensor + static pedestrian at 50m.

Thank you

Thank you for your earlier input.

Could you please advise what radar chip combinations (if any) can be considered together to address this challenge?
We shall explore multi-chip radar approaches that could enable both dynamic and stationary object detection with suitable configurations.

Please note, our preference is to proceed only with radar-specific chip combinations, not mixed with other sensing technologies.

Unfortunately, since a single chip can't support this use case, you would need to consider a multi sensor (cascaded) solution. Probably a 2x awr2243 or 4x awr2243 system.

Since these solutions are complex we recommend using a third party solution such as Smart Radar System | Main

We have a 2x2243 solution available, however it is not mature and we don't have benchmarks available.
