[QUESTION] How to identify duplicate paths with SBR method?

Hello, I have some questions about SBR in Raytracing. I have learned a lot from your documentation, one thing I’d like to understand is whether there is any mechanism in SBR to avoid calculating duplicate paths. As shown in the diagram, when I emit rays very densely from TX, let's assume Ray1 is the correct LOS path. Since Ray2 is very close to the receiver position, smaller than a preset threshold(max_dist in [Advanced Path Tracing](https://differt.eertmans.be/latest/notebooks/advanced_path_tracing.html#)), Ray2 seems to be mistakenly identified as an existing path. Is there any mechanism to avoid this error?
