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. Specifications Frequency: NATO D-Band (IEEE L-Band) pulse repetition frequency (PRF): 500 or 1000 Hz peak power: 150 kW average power: 5 kW Range: 140 nm range resolution: 0.5 nm beamwidth: 2.2° hits per scan: 15 - 20 antenna rotation: 7.5 or 15 rpm.
