AN/SPS-29 is a two-dimensional (giving only Range and Bearing) radar that was manufactured by General Electric. It was used by the US Navy as an early warning radar after World War II, and was equipped aboard naval ships during the Cold War. Variants include AN/SPS-29A, AN/SPS-29B, AN/SPS-29C, AN/SPS-29D and AN/SPS-29E.
This was a modified version of the AN/APS-2F radar, which the Weather Bureau acquired from the Navy. The WSR-1A, WSR-3, and WSR-4 were also variants of this radar. [88] This was followed by the WSR-57 (Weather Surveillance Radar – 1957) was the first weather radar designed specifically for a national warning network. Using WWII technology ...
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.
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The radar used a wavelength of about 10 cm. This corresponds to an operating frequency of 3.3 GHz. [3] This frequency is in the S band, which is also used by today's weather radar network. Dish diameter after modification was 6 feet (1.8 m) [1] The AN/APS-2F weighed 280 pounds (130 kg) (before modification). [3]
The AN/APQ-13 radar was an American ground scanning radar developed by Bell Laboratories, Western Electric, and MIT as an improved model of the airborne H2X radar, itself developed from the first ground scanning radar, the British H2S radar. It was used on B-29s during World War II in the Pacific theater for high altitude area bombing, search ...
These include a need to navigate "blind", when there is poor or no visibility at night or due to bad weather such as fog. [3] In addition to vessel-based marine radars, in port or in harbour, shore-based vessel traffic service radar systems are used by harbormasters and coast guard to monitor and regulate ship movements in busy waters.
The radar first flew in the third airframe, designated P2V-2S, which was the first one developed for the anti-submarine role. [35] Despite it being ineffectual when tracking periscopes, it proved effective at identifying large surface ships up to 200 nautical miles (370 km; 230 mi) away. [ 36 ]
