Synthetic-aperture radar ( SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or ...
A mass simulator named Gruzomaket (aka Kondor-E-GVM, COSPAR 2003-055A [3]) was launched on 5 December 2003, and almost ten years later on 27 June 2013, the first spacecraft was launched. Kondor No.202 (aka Kosmos 2487, Kondor 1, COSPAR 2013-032A [4]) was operated by the Russian military, [1] and carried a radar imaging payload. [5] It was the first radar imaging satellite to be operated by the ...
Inverse synthetic-aperture radar ( ISAR) is a radar technique using radar imaging to generate a two-dimensional high resolution image of a target. It is analogous to conventional SAR, except that ISAR technology uses the movement of the target rather than the emitter to create the synthetic aperture. [1] ISAR radars have a significant role aboard maritime patrol aircraft to provide them with ...
The Satellite Control Network ( SCN ), operated by the United States Space Force 's Space Delta 6, provides support for the operation, control, and maintenance of a variety of United States Department of Defense and some non-DoD satellites. This involves continual execution of Telemetry, Tracking, and Commanding (TT&C) operations. In addition, the SCN provides prelaunch checkout and simulation ...
NASA WorldWind is an open-source (released under the NOSA license and the Apache 2.0 license) virtual globe. According to the website ( https://worldwind.arc.nasa.gov/ ), "WorldWind is an open source virtual globe API. WorldWind allows developers to quickly and easily create interactive visualizations of 3D globe, map and geographical information.
Multistatic radar. A multistatic radar system contains multiple spatially diverse monostatic radar or bistatic radar components with a shared area of coverage. An important distinction of systems based on these individual radar geometries is the added requirement for some level of data fusion to take place between component parts.
MRMS is a system with automated algorithms that quickly and intelligently integrate data streams from multiple radars, surface and upper air observations, lightning detection systems, and satellite and forecast models.
Numerical weather prediction ( NWP) uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. Though first attempted in the 1920s, it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic results. A number of global and regional forecast models are run in different countries ...
