Over the horizon radar
WebOver-the-horizon radar ( OTH ), sometimes called beyond the horizon ( BTH ), is a type of radar system with the ability to detect targets at very long ranges, typically hundreds to thousands of kilometres, beyond the radar horizon, which is the distance limit for ordinary radar. Several OTH radar systems were deployed starting in the 1950s and ...
