The Sea-Based X-band radar (SBX-1) is a floating, self-propelled, mobile active electronically scanned array early-warning radar station designed to operate in high winds and heavy seas. It was developed as part of the United States Department of Defense Missile Defense Agency's (MDA) Ballistic Missile Defense System.
Diagram of AN/SPY-3 vertical electronic pencil beam radar conex projections. X band functionality (8 to 12 GHz frequency range) is optimal for minimizing low-altitude propagation effects, narrow beam width for best tracking accuracy, wide frequency bandwidth for effective target discrimination, and the target illumination for SM-2 and Evolved Sea Sparrow Missiles (ESSM).
Most merchant ships carry at least one of each type to ensure adequate target detection and response. [1] For example, the S-band operates better in sea clutter and rain than the X-band, however, the X-band has greater definition and accuracy in clear weather. [1] Radar is a vital navigation component for safety at sea and near the shore.
Marine radars are used by ships for collision avoidance and navigation purposes. The frequency band of radar used on most ships is X band (9 GHz/3 cm), but S band (3 GHz/10 cm) radar is also installed on most oceangoing ships to provide better detection of ships in rough sea and heavy rain condition.
The AN/SPS-49 is a United States Navy two-dimensional, long range air search radar built by Raytheon that can provide contact bearing and range. It is a primary air-search radar for numerous ships in the U.S. fleet and in Spain, Poland, Taiwan aboard Oliver Hazard Perry-class frigates, Canada on its Halifax-class frigate (prior to FELEX mid-life upgrade) and New Zealand on its Anzac-class ...
The antenna is mechanically steered, [4] uses a parabolic reflector, [5] and operates at 8 to 12 GHz (X Band). [2] [1] The system is a component of the Mk 99 fire-control system (FCS). [1] The first units were installed on the cruiser USS Ticonderoga, which was commissioned in 1983. Since then, the SPG-62 has been placed in service with many U ...
