    en.wikipedia.org/wiki/Over-the-horizon_radar

    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 were deployed starting in the 1950s ...

    Predel-E. 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] Predel-E relies on a phenomenon known as atmospheric ducting, where ...

    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, 2019. [5]

  5. Radar horizon - Wikipedia

    en.wikipedia.org/wiki/Radar_horizon

    The radar horizon is a critical area of performance for aircraft detection systems, defined by the distance at which the radar beam rises enough above the Earth 's surface to make detection of a target at the lowest level possible. It is associated with the low elevation region of performance, and its geometry depends on terrain, radar height ...

    e. 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]

    The elements appear to be a modified type of cage or bi-conical dipole providing wide operating bandwidth. Duga (Russian: Дуга́, lit. 'arc' or 'curve') was an over-the-horizon radar (OTH) system used in the Soviet Union as part of its early-warning radar network for missile defense. It operated from July 1976 to December 1989.

    en.wikipedia.org/wiki/Radar_MASINT

    MASINT radar sensors may be on space, sea, air, and fixed or mobile platforms. Specialized MASINT radar techniques include line-of-sight (LOS), over-the-horizon, synthetic aperture radar (SAR), inverse synthetic aperture radar (ISAR) and multistatic. It involves the active or passive collection of energy reflected from a target or object by LOS ...
