About Project:

Simrad HALO-3 Pulse Compression Radar


Combining the best characteristics of traditional pulse and FMCW broadband radar systems, Simrad Halo™ Radar uses Pulse Compression technology to provide an unprecedented mix of long and short detection range, high target definition, and minimal clutter in an affordable package for commercial operators. Solid State technology means minimal warm-up time and maximum ocean-going reliability, while compliance with upcoming Low Emission standards makes Halo Radar safe to run in ports and harbours.

  • True 48nm range with 3-foot open array antenna
  • Beam Sharpening with Target Separation Control
  • Compatible exclusively with Simrad NSS evo2 and NSO evo2 multifunction displays
  • Dual Range operation
  • Advanced signal processing with Custom, Harbour, Offshore, Weather, and Bird-finder modes
  • High-speed 48RPM operation
  • InstantOn™, ready in 16-25 seconds from power-on, instant from standby
  • MARPA target tracking, up to 10 targets (20 with dual range)*
  • Low electromagnetic emissions and radiation
  • Low power consumption with 12/24V operation
  • High reliability with solid-state electronics (no magnetron) and brushless motor
  • Ethernet connectivity
