It is true that the untrained LEO using radar can get false readings from wet leaves oscillating back and forth in wind. Years ago I had a chance to test this with an X band hand held unit and sure enough, pointing it down the road on a wet foliage day with no rain but a gentle breeze got me strange multiple speed readings with no vehicles in sight.
Does this happen with modern LEO equipment? I would think so on both X, K and Ka bands. Can anyone confirm that this can still happen?
Any other instances of false readings like the above from other conditions?
