Aperture masking interferometry — is a form of speckle interferometry, allowing diffraction limited imaging from ground based telescopes. This technique allows ground based telescopes to reach the maximum possible resolution, allowing ground based telescopes with large diameters… … Wikipedia
Range imaging — is the name for a collection of techniques which are used to produce a 2D image showing the distance to points in a scene from a specific point, normally associated with some type of sensor device.The resulting image, the range image , has pixel… … Wikipedia
Aperture (computer memory) — In computing, an aperture is a portion of the address space which is persistently associated with a particular peripheral device or a memory unit. Apertures may reach external devices such as ROM or RAM chips, or internal memory on the CPU itself … Wikipedia
Tactical Synthetic Aperture Radar — The Tactical Synthetic Aperture Radar (TSAR) is a new radar system introduced on the MQ 8B Fire Scout unmanned aerial vehicle. It delivers high resolution, wide area radar images day or night, and in all weather conditions. TSAR systems take… … Wikipedia
Synthetic aperture radar — (SAR) is a form of radar in which the highly directional (and thus very large) rotating antenna used by conventional radar is replaced with many low directivity small stationary antenna positions scattered over some area near or around the target … Wikipedia
Inverse synthetic aperture radar — (ISAR) is a technique to generate a two dimensional high resolution image of a target.In situations where other radars display only a single unidentifiable bright moving pixel, the ISAR image is often adequate to discriminate between various… … Wikipedia
Synthetic Aperture Radar — Radaraufnahme (SIR C/X SAR) des Vulkans Teide auf Teneriffa aus dem Space Shuttle Endeavour Ein Synthetic Aperture Radar (Abkürzung: SAR; deutsch etwa: „Radar mit synthetischer Apertur“) gehört zur Klasse der abbildenden Radare und wird als… … Deutsch Wikipedia
synthetic aperture radar — An airborne radar that produces an image of the scene that is similar to, but not identical with, an optical photograph. A cross range resolution obtained from a Doppler frequency, along with range resolution, forms the basis of a synthetic… … Aviation dictionary
Numerical aperture — The numerical aperture with respect to a point P depends on the half angle θ of the maximum cone of light that can enter or exit the lens. In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes… … Wikipedia
Very-small-aperture terminal — A 2.5 m parabolic dish antenna for bidirectional satellite Internet access A very small aperture terminal (VSAT), is a two way satellite ground station or a stabilized maritime Vsat antenna with a dish antenna that is smaller than 3 meters. The… … Wikipedia
