A standard SART 9 GHz radar transponder, produced by Jotron, on board a Norwegian ferry. The unit is 251 mm high. A search and rescue transponder (SART) is a self-contained, waterproof transponder intended for emergency use at sea. These devices may be either a radar-SART, or a GPS-based AIS-SART (automatic identification system SART).
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 L band (1 to 2 GHz) electronically scanned AEW and surveillance radar is located on a dorsal fin on top of the fuselage, dubbed the "top hat", and is designed for minimal aerodynamic effect. The radar is capable of simultaneous air and sea search, fighter control and area search, with a maximum range of over 600 km (look-up mode).
Since 1976 Falcon Field has been the home of Airbase Arizona, one of the largest units in the Commemorative Air Force (CAF) which operates a flying B-17G "Sentimental Journey" and a B-25J "Maid in the Shade" among other aircraft. On May 19, 2016, the Falcon Field World War II Aviation Hangars were listed in the National Register of Historic ...
Model airplane fields are used for landings and takeoffs of model aircraft.. Facilities provided vary significantly. They range from unimproved fields to paved runways.. Most model airfields in the United States have clubs chartered with the Academy of Model Aeronautics, similarly in Canada, their equivalent organization, the Model Aeronautics Association of Canada, provides the same function.
They sanction more than one thousand model competitions, and an increasing number of non-competitive Fly-in events for member aeromodelers throughout the country each year, charter more than 2500 model airplane clubs and offer contest sanctioning, liability insurance and the procurement of flying sites. They also certify official model flying ...

It may also be used at night time and during low visibility to monitor the movement of aircraft and vehicles. Surface movement radar is the term accepted by ICAO, but it has historically been known by other names such as ground movement radar, airport surface detection equipment (ASDE) and airfield surface movement indicator.
