We also saw radar detections frequently on ZF7982 and R500.
This behaviour was in buildings with multiple floors and multiple APs hearing each other
, together with a lot of wifi clients present. Outside business hours, there were no radar detection.
These were clearly false positives.
The APs interpreted certain type of RF energy as radar pulse and triggered radar detection.
Other vendors have/had this issue too. What to do?

- open a case
- use 20MHz wide channels for channel reuse
- use non-DFS channels as a workaround
