Is there a way to make the kernel export the pulse patterns when a
radar event is detected to do some debugging what was going on?

Anyway, you should compile ath9k with debugging support (which you most probably
already did) and enable DFS debugging by setting ATH_DBG_DFS (0x00010000) in
/sys/kernel/debug/ieee80211/phy0/ath9k/debug

This will give debug output per individual pulse and detector results and allow to
understand why the detector triggered.

Also if not already known, there is a dfs_stats file in the same debugfs directory
providing global DFS counters.


Hope it helps, have a nice weekend.

I already found the dfs_stats file, but the DFS debugging sounds
interesting. Thank you for the hint.
