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.
Commercial marine radar display. Land areas are shown in yellow, and vessel tracks are displayed with green "tails" on the screen. Marine radar systems can provide very useful radar navigation information for navigators on board ships. The ship's position could be fixed by the bearing and distance information of a fixed, reliable target on the ...
This act allowed Congress to appropriate $10,000 to established unmanned life-saving stations along the New Jersey coast south of New York Harbor and to provide "surf boat, rockets, carronades and other necessary apparatus for the better preservation of life and property from shipwreck ... ."
The central tower of each antenna system is 304 m (997.4 ft) tall. It is surrounded by six 266.7 m (875 ft) tall masts, placed on a ring with a radius of 556 m around the central tower. The remaining six towers of the array are 243.5 m (799 ft) tall, placed on a circle of 935.7 m (3,070 ft) around the central tower. [2]
This includes the AN/FPS-24 search radar tower that sits in a huge 64 foot square, 85 foot tall, six-story building. On top of this radar tower was a radar antenna 50 feet tall, 120 feet wide, weighing 85.5 tons, and rotating at 5 rpm. An available rigid radome 140 feet in diameter and 96 feet high protected this antenna from adverse weather ...
New site opened in October 1990, 1 mi (1.6 km) SE as an unattended NWS Short Range Radar site to cover any Long Range Radar surveillance gaps. The site consists of a radar tower, communications facility, and small storage building. Located near small village of Gjoa Haven, connected by gravel road to village 1.2 mi (1.9 km) south of site.
Most of the radars used at these ground stations were protected by rigid or inflatable radomes. The radomes were typically at least 15 m (50 ft) in diameter and the radomes were attached to standardized radar tower buildings that housed the radar transmitter, receiver and antenna. Some of these radomes were very large.
The antenna was smaller as it had to fit within a small area on the port side of the conning tower. In addition, the reduced height of the antenna installation impaired the range. Both U-boat versions had ranges of between 8 and 10 kilometres (5.0 and 6.2 mi) for naval targets and between 15 and 25 kilometres (9.3 and 15.5 mi) at an altitude of ...
