I have been working with your gr-radar toolbox, and I’ve been stuck on using the OS-CFAR block for multi peak detection.

I believe I have read every documentation, but still can’t figure out the problem.

If you have any insights on how to use the OS-CFAR block with the static target simulator for multiple simulated targets, I’d very much appreciate it.
