LW 08 “Jupiter”

The JUPITER/LW 08 2D-early warning radar performs long range (260 km on 2 m² RCS target) air surveillance on board medium and heavy-tonnage ships. JUPITER/LW 08 operates in D-Band, and is available with a cost-effective fully solid-state transmitter. The antenna is mounted on a lightweight hydraulically stabilised platform (roll and pitch).

The synthesiser-driven Traveling Wave Tube transmitter provides for a great flexibility over a wideband frequency, with pulse-to-pulse frequency agility. Together with the low sidelobe level of the antenna (with cosecant squared pattern) the radar has a high performance in an electronic countermeasures polluted environment. Excellent clutter suppression is the result of

LW 08 radars are installed aboard the German “Brandenburg” class frigates, too.
