Failure modes of radar sensor

Post by JohnnyGood1 » Mon Jul 09, 2018 4:38 pm

Hi everyone,

I got my hands on a Bosch mid-range radar (MRR) sensor that I believe belonged to a Tesla model S a while back. Now I'm working on a school project where we try to get the sensor to fail (i.e., output wrong or unusable data). Those of us involved in the project have defined a goal of understanding more about why radar fails in general but also what aspects of Bosch's specific sensor design might contribute to a failure.

So far, some preliminary research has revealed the following common failure types for automotive radars:

- External RF noise
- Ghost targets (e.g., multiple reflections from the same object resulting in targets with integer multiples of speed/distance)
- Obscurants on the sensor (e.g., snow, mud)

If anyone knows anything about other failure modes that exist, especially for Bosch radars and sensors, it would be interesting to discuss them on this thread.

Thanks!!

interesting. Is there code available to use this sensor?
