Simrad's New Halo Radar Refines Close and Long Distance Views

Simrad has officially unveiled its new Halo Pulse Compression Radar. The solid-state, open-array radar combines broadband radar and pulse radar to provide boaters visibility within the pulse radar's short distance blind spot. It also provides a long range look of up to 72 nautical miles away.

"The world of recreational radar has taken another quantum leap forward,' said Leif Ottosson, CEO of Navico, Simrad's parent company. "By introducing the HALO Pulse Compression Radar system, we have given boaters the best possible combination of features, providing the perfect mix of near and distant range, reliability and resolution without the associated warm-up time, power consumption, maintenance or harmful emissions.'

Halo Radar connects to any Simrad NSS evo2 or NSO evo2 multifunction display system via Ethernet, with a bulkhead-mounted RI-12 interface box below deck. Antenna installation has been simplified, utilizing the same thin cable and small-diameter connectors as the Broadband 3G and 4G radar systems.

Halo supports 12- or 24-volt systems and is available in three-, four- and six-foot open arrays. It incorporates Beam Sharpening for enhanced target separation control and improved target resolution. In its Dual Range mode, Halo can also function as two radars in one – monitoring two distance ranges simultaneously with independent display controls.

A Dual Range mode allows dual MARPA target tracking with a separate heading sensor. In fact, up to 20 targets can be tracked, displaying the closest point of approach and time to closest point of approach for each.

The system features Harbor, Offshore, Buoy, Weather, Bird, Netfinder, SaRT and Custom modes to better tune the system's signal processing to ensure targets are clearly identifiable in all environmental conditions.

Unlike some pulse radars, Halo does not rely on a high-powered magnetron or vacuum tube to transmit a signal – allowing it to produce a radar image instantly from standby and in 16 to 25 seconds after power-up. Navico says this is much faster than the typical two- to three-minute warm-up associated with many pulse radars.

For quieter operation, Halo features helical gear-train construction as well as a brushless motor. Navico says its solid-state technology is compliance with the latest low emission standards – making it safe to run Halo in anchorages and marinas. In standby mode, power consumption is said to be only seven watts, making it a friendlier system for small- to mid-sized powerboats.

The sleek open-array antenna sits atop a curved pedestal that's lit with a soft-glow, blue-LED accent light. The light can be customized with a four-level brightness control.

The new Simrad Halo Pulse Compression Radar is now available. The three-foot array is priced at US $4,500; the four-foot model is US $5,000, and the six-foot array is US $5,500.
