I have seen an article (sorry its Russian) claiming that low lying clouds have increased the distance of the radar reach from the normal 18 km till as far as 120 km. This allowed the military ship to be detected and sunk.
The source claims that the signal from the radar was reflected from the clouds to the water and vice versa. The clouds were very low, and the signal from this corridor between the water and the clouds had nowhere to go, hence the radar unexpectedly reached the target far beyond its usual range.
Is it physically possible? I know that short waves reflect from the ionosphere. But from the low lying clouds?
Pure physics please, this is not a political question.
