Simrad Halo 3 Pulse Compression Radar
Description
The Simrad Halo 3 is a complete open array pulse compression radar system built around a solid-state 25 W pedestal, a 3 ft antenna and the RI-12 interface module. The 3 ft array produces a 2.4 degree horizontal beam (sharpening to 1.7 degrees) and an instrumented range of up to 48 nautical miles, combining confident long-range detection with the clean close-in picture that pulse compression is known for.
Solid-state design means there is no magnetron to wear out and the system is ready to transmit in 16 to 25 seconds from power-on, while low-power pulsed transmissions make it safe to run in harbours and marinas. Antenna rotation is software-controlled at approximately 24 to 48 rpm, and the supplied RI-12 module brings NMEA 2000 and NMEA 0183 navigation data into the radar. Built to IEC60945 with IPX6 weatherproofing, the Halo 3 connects over Ethernet to compatible Simrad displays.
