ARTHUR is an acronym for "Artillery Hunting Radar", is a Counter-battery 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.

It is a mobile, passive electronically scanned array C-Band radar for the purpose of enemy field artillery acquisition and 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.

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.
