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.
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.
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).
X band is used in radar applications, including continuous-wave, pulsed, single-polarization, dual-polarization, synthetic aperture radar, and phased arrays. X-band radar frequency sub-bands are used in civil, military, and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defense tracking ...
A SART will only respond to a 9 GHz X-band (3 cm wavelength) radar. It will not be seen on S-band (10 cm) or other radar. Shipboard Global Maritime Distress Safety System (GMDSS) include one or more search and rescue locating devices. The radar-SART may be triggered by any X-band radar within a range of approximately 8 nautical miles (15 ...
AN/SPY-1D(V): Littoral Warfare Radar upgrade for the -1D variant applied to Arleigh Burke-class destroyers DDG 91 onwards, [13] Japanese Atago-class destroyers and Maya-class destroyers, South Korean Sejong the Great-class destroyers (KDX-III), Spanish F-105 frigate and the Australian Hobart-class air warfare destroyers (AWD).
APAR is typically paired with Thales Nederland's SMART-L passive electronically scanned array radar (which operates at L band frequencies). SMART-L is a long-range Volume Search Radar (VSR) that is able to provide volume search and tracking out to 480 km. The whole system is called Anti-Air Warfare Systems (AAWS), and is based on the NATO Anti ...
