Simrad 000-11464-001 HALO 3-Foot Open Array Radar Antenna

The Simrad 000-11464-001 is the 3-foot open array antenna for the Simrad HALO Pulse Compression Radar system. Engineered for recreational and light commercial marine use, this solid-state radar antenna delivers an exceptional combination of short- and long-range detection — covering targets from as close as 6 meters (20 feet) out to 48 nautical miles — without the warm-up time, high power consumption, or electromagnetic emissions of traditional magnetron pulse radar.

Key Features:

• Pulse Compression Technology: Combines the best of traditional pulse and FMCW broadband radar for superior target definition and minimal clutter at both short and long range
• 48nm Maximum Range: True 48-nautical-mile range with the 3-foot open array antenna
• 2.4° Horizontal Beam Width: Narrows to 1.7° with Beam Sharpening mode active, delivering target separation equivalent to a larger 4-foot array
• InstantOn™ Technology: Ready from standby instantly; fully operational in just 16–25 seconds from a cold power-on — no 2–3 minute magnetron warm-up wait
• High-Speed 48RPM Operation: Rapid position updates with mode- and range-dependent high-speed rotation; brushless motor with helical geartrain ensures exceptionally quiet operation
• Advanced Signal Processing: Digital azimuth and range sidelobe reduction enhances discrimination of small targets (e.g., channel markers) from larger adjacent targets (e.g., bridges, ships)
• Directional Sea Clutter Rejection: Dynamically adjusts gain to allow smaller targets to be detected in difficult sea conditions
• MARPA Target Tracking: Track up to 10 user-selected radar targets with CPA (closest point of approach) and TCPA (time to closest point of approach) data; up to 20 targets in Dual Range mode
• Dual Range Mode: Functions like two radar arrays in one — monitor two distances simultaneously with independent displays, controls, and MARPA tracking
• Preset Operating Modes: Harbour, Offshore, Weather, Bird, and Custom modes for optimized performance in different environments
• Low RF Emissions: 25W solid-state GaN technology; safe to operate in anchorages and marinas
• Ethernet Connectivity: Connects to Simrad NSS evo2 or NSO evo2 multifunction display systems via Ethernet with a bulkhead-mounted interface box
• Blue LED Accent Lighting: Soft-glow dual-beam LED lighting integrated into the pedestal with 4-level brightness control
• Low Maintenance: No magnetron to replace, no manual tuning, and a solid-state brushless motor driver eliminates brush wear
