Metox Radar Detector
The R600A Metox, named after its manufacturer, was a pioneering high-frequency radar warning receiver (RWR) used by the German forces on U-boats from 1942–1945. It was initially installed to receive signals transmitted by British radars. Manufacture and purpose The Metox was manufactured by a small French company in occupied Paris. It was tuned to receive the signals used by many British radars of the early and mid-Second World War, notably the ASV Mk. II radar used by RAF Coastal Command to detect U-boats. It is not clear whether the design was German or French or both. It was installed on German U-boats starting in 1942 and used until the end of the war. The system given the official title of (FuMB 1, adio measuring device. British radar From July 1940, the British fitted the RAF Mk II AI (Airborne Interception) radar into Coastal Command aircraft for use as the Mk II "-metre ASV". The radar suffered from problems due to land clutter and inability to determine height, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay Of Biscay
The Bay of Biscay ( ) is a gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Point Penmarc'h to the Spanish border, and along the northern coast of Spain, extending westward to Cape Ortegal. The average depth is and the greatest depth is . Etymology The Bay of Biscay is known in Spain as the Gulf of Biscay (; ). In France, it is called the Gulf of Gascony ( ; ; ; ). In Latin, the bay was known as ( Cantabrian Gulf); the name Cantabrian Sea is still used locally for the southern area of the Bay of Biscay that washes over the northern coast of Spain ( Cantabria). The English name comes from Biscay on the northern Spanish coast, probably standing for the western Basque districts (''Biscay'' up to the early 19th century). Geography Parts of the continental shelf extend far into the bay, resulting in fairly shallow waters in many areas and thus the rough seas for which the region is known. Heavy storms ...

Radar Warning Receivers
Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat. RWR systems can be installed in all kind of airborne, sea-based, and ground-based assets such as aircraft, ships, automobiles, military bases. Depending on the market the RWR system is designed for, it can be as simple as detecting the presence of energy in a specific radar band, such as the frequencies of known surface-to-air missile systems. Modern RWR systems are often capable of classifying the source of the radar by the signal's strength, phase and signal details. The information about the signal's strength and waveform can then be used to estimate the type of threat the detected radar poses. Description The RWR usually has a visual display somewhere prominent in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II German Radars
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, ...

U-boats
U-boats are naval submarines operated by Germany, including during the First and Second World Wars. The term is an anglicized form of the German word , a shortening of (), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also known as U-boats. U-boats are most known for their unrestricted submarine warfare in both world wars, trying to disrupt merchant traffic towards the UK and force the UK out of the war. In World War I, Germany intermittently waged unrestricted submarine warfare against the UK: a first campaign in 1915 was abandoned after strong protests from the US but in 1917 the Germans, facing deadlock on the continent, saw no other option than to resume the campaign in February 1917. The renewed campaign failed to achieve its goal mainly because of the introduction of convoys. Instead the campaign ensured final defeat as the campaign was a contributing factor to the entry of the US in the First World War. In World War II, ...

H2X Radar
H2X, eventually designated as the AN/APS-15, was an American ground scanning radar system used for blind bombing during World War II. It was developed at the MIT Radiation Laboratory under direction of Dr. George E. Valley Jr. to replace the less accurate British H2S radar, the first ground mapping radar to be used in combat. H2X was also known as the "Mickey set" and "BTO" for "bombing through the overcast" radar. H2X differed from the original H2S primarily in its 3-cm wavelength X band rather than H2S' 10-cm S band. This shorter wavelength gave H2X higher resolution than H2S, allowing it to provide usable images over large cities which appeared as a single blob on the H2S display. The Royal Air Force (RAF) initially considered using H2X as well, but would instead develop their own X band system, the H2S Mk. III. The RAF system entered service in late 1943, before the first use of H2X in early 1944. The desire for even higher resolution, enough to image individual docks ...

Naxos Radar Detector
The Naxos radar warning receiver was a World War II German countermeasure to S band microwave radar produced by a cavity magnetron. Introduced in September 1943, it replaced Metox, which was incapable of detecting centimetric radar. Two versions were widely used, the FuG 350 Naxos Z that allowed night fighters to home in on H2S radars carried by RAF Bomber Command aircraft, and the FuMB 7 Naxos U for U-boats, offering early warning of the approach of RAF Coastal Command patrol aircraft equipped with ASV Mark III radar. A later model, Naxos ZR, provided warning of the approach of RAF night fighters equipped with AI Mk. VIII radar. Background Prior to the introduction of the cavity magnetron, radar systems used traditional vacuum tube electronics and were limited to about 1.5 m wavelength in UK use, and as low as 50 cm in German systems. Both could receive the transmissions of their opposing radar systems and radar warning receivers were widely used by both sides in a numb ...

Submarine Snorkel
A submarine snorkel is a device which allows the engine of a submarine to operate Underwater, submerged while still taking in air from above the surface. British Royal Navy personnel often refer to it as the snort. A concept devised by Dutch engineers, it was widely used on German U-boats during the last year of World War II and known to them as a . History Until the advent of Nuclear submarine, nuclear power, submarines were designed to operate on the surface most of the time and submerge only for evasion or for daylight attacks. Until the widespread use of radar after 1940, at night a submarine was safer on the surface than submerged, because sonar could detect boats underwater but was almost useless against a surface vessel. However, with continued radar improvement as the war progressed, submarines (notably, the Germany, German U-boat, U-boats in the Battle of the Atlantic) were forced to spend more time underwater, running on electric motors that gave speeds of only a fe ...

Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in Armored car (military), armoured vehicles. More complex periscopes using Prism (optics), prisms or advanced Optical fiber, fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. ...

H2S Radar
H2S was the first airborne radar system, airborne, Airborne ground surveillance, ground scanning radar system. It was developed for the Royal Air Force's RAF Bomber Command, Bomber Command during World War II to identify targets on the ground for night and all-weather bombing. This allowed attacks outside the range of the various radio navigation aids like Gee (navigation), Gee or Oboe (navigation), Oboe, which were limited to about of range from various base stations. It was also widely used as a general navigation system, allowing landmarks to be identified at long range. In March 1941, experiments with an early aircraft interception radar based on the 9.1 cm wavelength, S band, (3 GHz) cavity magnetron revealed that different objects have very different radar signatures; water, open land and built-up areas of cities and towns all produced distinct returns. In January 1942, a new team was set up to combine the magnetron with a new scanning antenna and plan position indic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
