The SCR-584 (short for Set, Complete, Radio # 584) was an automatic-tracking microwave radar developed by the MIT Radiation Laboratory during World War II.It was one of the most advanced ground-based radars of its era, and became one of the primary gun laying radars used worldwide well into the 1950s.
Targeting radars utilize the same principle but scan smaller volumes of space far more often, usually several times a second or more, while a search radar will scan a larger volume less frequently.
SJ radar was a type of S band (10-cm) radar set used on American submarines [3] during the Second World War. [4] The widespread use of the SJ radar, combined with the very low use of radar in the Imperial Japanese Navy, gave great operational flexibility to the United States Navy's submarine campaign in the Pacific Ocean.
SMART-S Mk2 [2] [5] [4] (Signaal Multibeam Acquisition Radar for Tracking, S band Mk2) is a naval medium to long-range air and surface surveillance multibeam passive electronically scanned array 3D radar designed by Thales Nederland, [6] formerly Hollandse Signaalapparaten (Signaal). While the original SMART-S radar was only produced in small ...
Tethered Aerostat Radar System in New Mexico. The first aerostats were assigned to the United States Air Force in December 1980 at Cudjoe Key, Florida.During the 1980s, the U.S. Customs Service operated a network of aerostats to help counter illegal drug trafficking.
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
The power was doubled by using two tubes, and in mid-1936, the equipment was set up on cliffs near Kiel, and good detections of ships at 7 km (4.3 mi) and aircraft at 4 km (2.5 mi) were attained. The success of this experimental set was reported to the Kriegsmarine , but they showed no interest; they were already fully engaged with GEMA for ...
Secondary surveillance radar antenna (flat rectangle, top) mounted on an ASR-9 primary airport surveillance radar antenna (curved rectangle, bottom).. The need to be able to identify aircraft more easily and reliably led to another wartime radar development, the Identification Friend or Foe (IFF) system, which had been created as a means of positively identifying friendly aircraft from unknowns.
