Moving target indication — (MTI) is a mode of operation of a radar to discriminate a target against clutter. [1] In contrast to another mode, stationary target indication, it takes an advantage of the fact that the target moves with respect to stationary clutter. The most… … Wikipedia
Aperture synthesis — or synthesis imaging is a type of interferometry that mixes signals from a collection of telescopes to produce images having the same angular resolution as an instrument the size of the entire collection. At each separation and orientation, the… … 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
Interferometric synthetic aperture radar — Interferometric synthetic aperture radar, also abbreviated InSAR or IfSAR, is a radar technique used in geodesy and remote sensing. This geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface… … 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 — 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
