It was a very specific and unusual set of circumstances, as I mentioned. Not sure why it decided that a hovering helo was the target it was looking for, but there you so.

Oh, and detecting helos that are using active dipping sonar? That's a thing. Same principles behind detecting anything else that transmits an active pulse.
