Simrad 000-11465-001 Halo-4 Pulse Compression Radar Antenna Array 4 Foot

The Simrad Halo-4 Radar Antenna Array combines the best characteristics of traditional pulse and Frequency Modulated Continuous Wave broadband radar systems. Using advanced Pulse Compression technology, this 4-foot open array delivers an unprecedented mix of long and short detection range with high target definition and minimal clutter. With a maximum range of 64nm true range and a horizontal beamwidth of 1.8° (enhanced to 1.6°/1.4°/1.2° with Beam Sharpening), the Halo-4 provides exceptional target discrimination.

Key Features:

• Pulse Compression Technology: Solid-state X-Band radar with 25W transmit power provides superior long-range detection and short-range target definition without the clutter of traditional systems
• InstantOn Operation: Ready in just 16-25 seconds from power-on and instantly from standby—no 2-3 minute warm-up required like traditional pulse radar
• High-Speed 48RPM Operation: Rapid position updates with exceptionally quiet brushless motor and advanced helical geartrain design
• Advanced Signal Processing: Digital azimuth and range sidelobe reduction enhances discrimination of small targets like channel markers from larger adjacent targets. Directional Sea Clutter Rejection dynamically adjusts gain to reveal smaller targets in the leeward
• MARPA Target Tracking: Track up to 10 user-selected radar targets with CPA and TCPA data (requires heading sensor and GPS)
• Low Emissions and Power Consumption: Safe for use in anchorages and marinas with low-power pulse transmission. Minimum safe distance is within the antenna's swing circle. Draws only 40W average with zero wind, 150W peak at 70 knots, and just 6.5W in standby
• Multiple Operating Modes: Automatic Harbor, Offshore, Weather, and BIRD modes, plus Custom manual mode and Dual Range capability
• Premium Aesthetics: Soft-glow dual-beam Blue LED accent lighting integrated into pedestal with 4-level brightness control
