Yes it is for those who are near one of the 9 weather radar sites sites. You're lucky you're not near one!

 

Obviously if you're indoors it's also much less likely to be an issue unlike outdoor usage where it can cause interference.

 

Also plenty of false positives on the radar detection too. I cant have 2 APs on the same DFS set of channels or things keep having radar detected all the time.
