AWR1642BOOST: detect objects in tunnel

Hello Marcin,

Yes, it is possible to use a TI mmWave device to achieve the objective you've described.

This demo video shows a slow moving car detecting static objects (relevant video starts at 59sec): 

I would suggest checking out the Short Range Radar demo for an example of free space determination: 

The software for SRR:

Accuracy of a few cms could be possible but this would be dependent on the chirp configuration used to configure the device. Also the ability to detect an object is  in part determined by the size and material of the object.

The sensing estimator tool can help with estimating detection parameters: 

Best,

Amanda

Thank you for your answer. I also saw this video: training.ti.com/robotics-sense-and-avoid-demonstration-using-ti-mmwave-sensors. On this video, the robot detects obstacles in a very small range by analyzing the point cloud data. I think this may could be the solution for me, because the point cloud data will determine free space in the front. What is the accuracy of measuring the distance of points and the accuracy of the angle of points on a distance of about 5m in this solution? Can this solution with a point cloud data have a range of up to 10m and accuracy of 1 or 2 centimeters on 5m distance? And what set of evaluation board will give me greater accuracy at this small distance? xWR1642 or xWR1443 or other?
