The Super Fledermaus radar, at the EME (Electrical & Mechanical Engineers) Equipment Display on 21 November 2004 in Hyderabad. This radar is used in 35mm air defence batteries and designed to detect low-flying objects, such as unmanned air vehicles (UAVs). The digital system contains a built-in simulator as well as a signal jammer. The radar was acquired in the early 1980s and produced by BEL under license from the radar's designer, Ericsson Radar Electronics of Sweden. Upgraded by BEL in 2001, the Super Fledermaus now features a highly capable tracking radar with significant capability against difficult, low-flying targets such as cruise missiles. The upgraded radar has a range of 56 miles (90 km) and is fitted with a new digital fire control computer.
