I am using MUSIC algorithm for radar angle estimation project. However, it will show a mirror target when the target is near the angle limit. I found the same issue in the Radar Signal Simulation and Processing for Automated Driving demo.

Can anyone explain this to me? Or how can we solve this issue in tracking?

The range angle image you mentioned in question is not a mirrored target, rather it's just an aliasing to the opposite side due to the low angular resolution. Do you have an example for the case in MUSIC?

That blob has only one peak so even though it looks like two targets, when we do the detection, only one peak is identified and that's what gets passed to the tracker.

Thank you very much.
