MADRE over-the-horizon radar at the NRL's Chesapeake Bay Detachment U.S. Navy Relocatable Over-the-Horizon Radar station. The most common type of OTH radar, OTH-B (backscatter), [3] uses skywave or "skip" propagation, in which shortwave radio waves are refracted off an ionized layer in the atmosphere, the ionosphere, and return to Earth some distance away.
The Jindalee Operational Radar Network (JORN) is an over-the-horizon radar (OHR) network operated by the Royal Australian Air Force (RAAF) that can monitor air and sea movements across 37,000 square kilometres (14,000 sq mi). [citation needed] It has a normal operating range of 1,000–3,000 kilometres (620–1,860 mi). [1]
Container (29B6) radar (Russian: 29Б6 «Контейнер») is the new generation of Russian over-the-horizon radar, providing long distance airspace monitoring and ballistic missile detection. The first radar, near Kovylkino , Mordovia , Russia , became operational in December 2013 [ 1 ] [ 3 ] [ 4 ] and entered combat duty on 1 December ...

Cobra Mist was the codename for an Anglo-American experimental over-the-horizon radar station at Orford Ness, England. [a] It was known technically as AN/FPS-95 and sometimes referred to as System 441a; a reference to the project as a whole. Cobra Mist was part of a small number of "Cobra" long-range surveillance radars operated by the United ...
Predel-E (in Russian: Предел-Э [1]) is a Russian military over-the-horizon radar system shown since 2017, [2] designed to detect ships in coastal areas. [3]It was developed by Concern Morinformsystem-Agat, with at least one variant designed by NPP Salyut. [3]
It has a range of up to 10,000 km and is capable of simultaneously tracking 500 objects. [7] [8] Its horizon range is 6000 km and vertical range is 8000 km (due to radar horizon, this range is only applicable if target is located at altitude of several kilometers [citation needed]).
An over-the-horizon radar sited in the USSR would help solve this problem, and work on such a system for this associated role started in the late 1960s. The first experimental system, Duga, was built outside Mykolaiv in Ukraine , successfully detecting rocket launches from Baikonur Cosmodrome at 2,500 kilometres (1,600 mi).
