It featured a 75 cm (30 in) rotating radar dish that operated at 13.4 GHz (K u band). [2] It could collect data between 51.6 degrees north and south latitude, with a swath 900 km wide (560 mi). [3] The ISS-RapidScat program was initiated in response to the failure of the QuikSCAT satellite's antenna rotation mechanism in November 2009. While ...
A satellite finder (or sat finder) is a satellite field strength meter used to accurately point satellite dishes at communications satellites in geostationary orbit. [ 14 ] [ 15 ] [ 16 ] Professional satellite finder meters allow better dish alignment and provide received signal parameter values as well.
The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased-array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

Satellite laser ranging is a proven geodetic technique with significant potential for important contributions to scientific studies of the earth/atmosphere/ocean system. It is the most accurate technique currently available to determine the geocentric position of an Earth satellite, allowing for the precise calibration of radar altimeters and ...
The secondary radar antenna array rides atop the primary radar dish at the radar site, with both rotating at approximately 12 revolutions per minute. The Digital Airport Surveillance Radar (DASR) is a newer TRACON radar system, replacing the old analog systems with digital technology. The civilian nomenclature for these radars is the ASR-9 and ...
The radar antennas are located in Tromsø, Norway; Sodankylä, Finland and Kiruna, Sweden, north of the Scandinavian Arctic Circle. The core in the tri-static system, is located at Ramfjordmoen, outside Tromsø, Norway with a 32 meter mechanically fully steerable parabolic dish used for transmission and reception in the UHF-band. Operating in ...

Imaging radar is an application of radar which is used to create two-dimensional images, typically of landscapes. Imaging radar provides its light to illuminate an area on the ground and take a picture at radio wavelengths. It uses an antenna and digital computer storage to record its images.
