LW 08 “Jupiter”

The JUPITER/LW 08 is a 2D D-band naval early warning radar designed for long-range air surveillance on medium and heavy-tonnage ships, capable of detecting a 2 square meter radar cross-section target at 260 km. It features a hydraulically stabilized antenna platform and a synthesizer-driven Traveling Wave Tube transmitter, offering pulse-to-pulse frequency agility across a wideband frequency. This, combined with the antenna's cosecant-squared pattern and low sidelobe levels, provides high performance in electronic countermeasures environments and excellent clutter suppression. Developed by Hollandse Signaalapparaten under the internal designation DRBV 26, it was subsequently known as TRS 3010 after acquisition by Thomson-CSF, and later JUPITER/LW 08 under Thales, with a land-based civilian air traffic control version designated LAR-2 and the Royal Canadian Navy designation AN/SPQ-502. It is notably installed on German Brandenburg-class frigates.
