ARTHUR is an acronym for "Artillery Hunting Radar", a mobile passive electronically scanned array C-Band radar system originally developed jointly for and in close co-operation with the Norwegian and Swedish armed forces by Ericsson Microwave Systems in both Sweden and Norway. This field artillery acquisition radar was developed for the primary role as the core element of a brigade or division level counter battery sensor system. The vehicle carrying the radar was originally a Bandvagn 206 developed and produced by Hägglunds, but is now more often delivered on trucks with ISO fasteners. The radar is now developed by SAAB Electronic Defence Systems (after EMW was sold to SAAB in June 2006) and Saab Technologies Norway AS. ==Deployment== The ARTHUR detects hostile artillery by tracking projectiles in flight. The original ARTHUR Mod A can locate guns at 15 - 20 km and 120 mm mortars at 30 - 35 km with a circular error probable of 0.45% of range. This is accurate enough for effective counter-battery fire by friendly artillery batteries. ARTHUR can operate as a stand-alone medium-range weapons locating radar or a long-range weapon locating system, consisting of two to four radars working in coordination. This flexibility enables the system to maintain a constant surveillance of an area of interest. The upgraded ARTHUR Mod B meets the British Army's MAMBA requirement for locating guns, mortars or rockets. It can locate guns at 20 - 25 km and 120 mm mortars at 35 - 40 km with a circular probable error of 0.35% of range. MAMBA was successfully used by the British Army in Iraq and Afghanistan. ARTHUR Mod C has a larger antenna and can detect guns at 31 km, mortars at 55 km and rockets at 50 - 60 km depending on their size, and locate targets at a rate of 100 per minute with CEP 0.2% of range for guns and rockets and 0.1% for mortars. It can be carried by a C-130 or slung under a heavy lift helicopter such as a Chinook. Its air mobility allows it for use by light and rapid reaction forces such as airborne and marine units. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ARTHUR (radar)」の詳細全文を読む スポンサード リンク
