Oth-b radar
WebThe facility was the transmitting unit of a radar defense system and was composed of 216 antennae that range from 35 to 135 feet high. The station was the product of research in an over-the-horizon backscatter radar (OTH-B) system that had been developed in the early 1970s at the Air Force Rome Air Development Center, a research center in New York. Over-the-horizon radar (OTH), sometimes called beyond the horizon radar (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 … See more The frequency of radio waves used by most radars, in the form of microwaves, travel in straight lines. This generally limits the detection range of radar systems to objects on their horizon (generally referred to as "line of sight" … See more UK/US Cobra Mist The first truly operational development was an Anglo-American system known as Cobra Mist, which began construction in the late 1960s.
