Andre-It isn't quite the same. Google "radar over the horizon" to see how extensive this is these days. I don't know if this was being exploited at all in WW2 but suspect even then, the radar horizon was known to be beyond the visual horizon. Radio waves tend to skip and bounce, so even then the engineers would have been aware that they could exceed visual horizons, even if only slightly.
