Predel-E
Predel-E (in Russian: Предел-Э) is a Russian military over-the-horizon radar system shown since 2017, designed to detect ships in coastal areas. It was developed by Concern Morinformsystem-Agat, with at least one variant designed by NPP Salyut. Predel-E relies on a phenomenon known as atmospheric ducting, where certain meteorological conditions create a waveguide A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency w ... at a height of up to several dozen meters above the surface, which significantly increases the range of radar signals above 3 GHz, allowing Predel-E to detect targets at a distance of over 400 km, according to the manufacturer. Predel-E is designed to support the K-300P Bastion-P missile system and other systems. In August 2023, Ukraine's military announ ...

Concern Morinformsystem-Agat
Concern Morinformsystem-Agat is a Russian joint stock company that engages in the development and production of integrated structures for the military-industrial sector in the Russian Federation and internationally. The original company was established in 1942 as a Special Design Bureau (SDB) of the People's Commissariat of the Shipbuilding Industry of the USSR. Morinformsystem-Agat manufactures equipment and instruments for warships. Scientific Production Association Agat is the core company of the concern. Its products include the Klub-S and Klub-N missile fire-control systems, Bal-E missile systems, MR-123 and Puma ( 5P-10) artillery systems, and radar stations such as the Predel-E coastal 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 t ... system.

Atmospheric Ducting
In telecommunications, an atmospheric duct is a horizontal layer in the lower atmosphere in which the vertical refractive index gradients are such that radio signals (and light rays) are guided or ducted, tend to follow the curvature of the Earth, and experience less attenuation in the ducts than they would if the ducts were not present. The duct acts as an atmospheric dielectric waveguide and limits the spread of the wavefront to only the horizontal dimension. Atmospheric ducting is a mode of propagation of electromagnetic radiation, usually in the lower layers of Earth’s atmosphere, where the waves are bent by atmospheric refraction. In over-the-horizon radar, ducting causes part of the radiated and target-reflection energy of a radar system to be guided over distances far greater than the normal radar range. It also causes long-distance propagation of radio signals in bands that would normally be limited to line of sight. Normally radio "ground waves" propagate along the ...

K-300P Bastion-P
The K-300P ''Bastion-P'' (NATO reporting name SS-C-5 Stooge) is a Russian mobile coastal defence missile system. The system was developed together with the Belarusian company '' Tekhnosoyuzproekt''. Design The main role of the Bastion-P is to engage surface ships including carrier battle groups, convoys, and landing craft. A typical battery is composed of 1-2 command and control vehicles based on the Kamaz 43101 6×6 truck, one support vehicle, four launcher vehicles based on the MZKT-7930 8×8 chassis each operated by a 3-man crew and holding two missiles, and four loader vehicles; launcher vehicles can be located up to away from the C2 vehicles. Upon halting, missiles can be readied for firing within five minutes, and both fired in 2-5 second intervals. The mobile launcher can remain on active standby over a period of 3–5 days, or up to 30 days when accompanied by a combat duty support vehicle. - Military-Today.com

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 and 1960s as part of early-warning radar systems, but Airborne early warning and control, airborne early warning systems have generally replaced these. OTH radars have recently been making a comeback, as the need for accurate long-range tracking has become less important since the ending of the Cold War, and less-expensive ground-based radars are once again being considered for roles such as maritime reconnaissance and drug enforcement. Technology The frequency of radio waves used by most radars, in the form of microwaves, propagate in straight lines. This generally limits the detection range of radar systems to objects on their Radar horizo ...

Waveguide
A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency waveguides which direct electromagnetic waves other than light like radio waves. Without the physical constraint of a waveguide, waves would expand into three-dimensional space and their intensities would decrease according to the inverse square law. There are different types of waveguides for different types of waves. The original and most common meaning is a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves. Dielectric waveguides are used at higher radio frequencies, and transparent dielectric waveguides and optical fibers serve as waveguides for light. In acoustics, air ducts and horns are used as waveguides for sound in musical instruments and loudspeakers, and specially-shaped metal rod ...

Kherson Oblast
Kherson Oblast (, ; ), also known as Khersonshchyna (, ), is an administrative divisions of Ukraine, oblast (province) in southern Ukraine. It is located just north of Crimea. Its administrative center is Kherson, on the northern or right bank of the Dnieper river, which bisects the oblast. The oblast has an area of 28,461 km2 and a population of It is considered the 'fruit basket' of the country, as much of its agricultural production is dispersed throughout the country, with production peaking during the summer months. Most of the area of the Russian occupation of Kherson Oblast, oblast has been under Russian military occupation since early in the 2022 Russian invasion of Ukraine. In September 2022, Russia claimed to have Annexation of Southern and Eastern Ukraine, annexed Kherson Oblast after arranging a 2022 annexation referendums in Russian-occupied Ukraine, disputed referendum. The referendum and the subsequent claimed annexation are internationally unrecognized. As ...
