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.

The development of this radar started in the company Hollandse Signaalapparaten. There this radar got the company internal designation DRBV 26. After the acquisition of Signaal by Thomson-CSF, this radar got a new name: TRS 3010. Later Thomson-CSF was also acquired by Thales. Here the radar was produced under the name JUPITER/LW 08. LAR-2 is a land-based civilian ATC version of the LW 08.
