Signaal LW 08 radar

The antenna of the Signaal LW 08 radar aboard HS Kanaris, F464, a Kortenaer-Standard class frigate.

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 UHF L-Band (NATO D-band, 1–2 GHz). The antenna is mounted on a lightweight hydraulically stabilised platform (roll and pitch).

The synthesiser-driven TWT 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. Good clutter suppression is the result of

* the applications of antenna stabilisation,
* a receiver with a high dynamic range,
* quadrature digital moving target indication processing,
* use of circular polarisation.
