Established in 1915, the company has produced a wide variety of products including marine electronics, measuring equipment for telecommunication, radio broadcasting equipment, and amateur radio equipment, including the JST-145dx/JST-245dx HF transceivers, which were the last amateur radio transceivers produced by JRC, ending in 2002.
An ATC ground station consists of two radar systems and their associated support components. The most prominent component is the PSR. It is also referred to as skin paint radar because it shows not synthetic or alpha-numeric target symbols, but bright (or colored) blips or areas on the radar screen produced by the RF energy reflections from the target's "skin."
AN/SPY-1D(V): Littoral Warfare Radar upgrade for the -1D variant applied to Arleigh Burke-class destroyers DDG 91 onwards, [13] Japanese Atago-class destroyers and Maya-class destroyers, South Korean Sejong the Great-class destroyers (KDX-III), Spanish F-105 frigate and the Australian Hobart-class air warfare destroyers (AWD).
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.
Marine radar has performance adjustment controls for brightness and contrast, also manual or automatic adjustment of gain, tuning, sea clutter and rain clutter suppression, and interference reduction. Other common controls consist of range scale, bearing cursor, fix/variable range marker (VRM) or bearing/distance cursor (EBL).
The receiver electronics unit has been upgraded to a fully channelized digital architecture with dual 32-bit processors, yet with an overall reduction in system size and weight. The Azimuth Display Indicator (ADI) is a 3 in (76.2 mm) diameter CRT or LCD cockpit display, carried over from the AN/ALR-67(V)2, used to show intercepted threats.
The AN/SPS-52 is a United States Navy long-range air search 3D radar that is capable of providing contact bearing, range and altitude. It was used on Baleares and Brooke-class frigates, Charles F. Adams and Hatakaze-class destroyers, Tarawa and Wasp-class amphibious assault ships, Galveston, and Providence-class cruisers and other ships.
It is installed as an anti-water search radar on the Maritime Self-Defense Force's escort ship. [1] Variations include OPS-18-1 and OPS-18-3 . The model numbers of the Maritime Self-Defense Force's electronic devices, including this machine, are generally based on the naming rules for military electronic devices of the U.S. military.
