Aerospace Data Facility-Southwest (ADF-SW) is one of three satellite ground stations operated by the National Reconnaissance Office (NRO) in the continental United States.
The radar was run by NASA's Space Radar Laboratory. SIR utilizes 3 radar frequencies: L band (24 cm wavelength), C band (6 cm) and X band (3 cm), [1] allowing for study of geology, hydrology, ecology and oceanography. Comparing radar images to data collected by teams of people on the ground as well as aircraft and ships using simultaneous ...
It uses an antenna and digital computer storage to record its images. In a radar image, one can see only the energy that was reflected back towards the radar antenna. The radar moves along a flight path and the area illuminated by the radar, or footprint, is moved along the surface in a swath, building the image as it does so. [1] Digital radar ...
An example is TerraSAR-X, which is a German Earth-Observation satellite. Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to provide multiple imaging modes for recording images with different swath width, resolution and polarizations, see the figure for more details.
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.
Side-looking airborne radar (SLAR) is an aircraft, [1] or satellite-mounted imaging radar pointing perpendicular to the direction of flight (hence side-looking). [2] A squinted (nonperpendicular) mode is also possible. SLAR can be fitted with a standard antenna (real aperture radar) or an antenna using synthetic aperture.
Incredible satellite footage captures the Pacific Palisades wildfares rage across Los Angeles. Bright orange flames and thick smoke can be seen from the skies, in the footage shared by CIRA on ...
The image almost certainly came from a satellite known as USA 224, according to Marco Langbroek, a satellite tracker based in the Netherlands. The satellite was launched by the National Reconnaissance Office in 2011. [45] On January 31, 2020, Rocket Lab successfully launched a NROL-151 payload for the NRO. [46]
