O que (quem) é synthetic aperture - definição

MIXING SIGNALS FROM MANY TELESCOPES TO PRODUCE IMAGES WITH HIGH ANGULAR RESOLUTION

Aperture Synthesis; Synthetic aperture; Synthesis imaging; Synthetic Aperture; Uv-plane; Interferometric imaging

Aperture synthesis

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 lobe-pattern of the interferometer produces an output which is one component of the Fourier transform of the spatial distribution of the brightness of the observed object.

Inverse synthetic-aperture radar

Inverse Synthetic aperture radar; Inverse Synthetic Aperture Radar; Inverse SAR; Inverse synthetic aperture radar

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.

Synthetic Aperture Personality Assessment

User:Dc023/Synthetic Aperture Personality Assessment

Synthetic Aperture Personality Assessment (SAPA) is a method used for telemetric assessment of individual differences, primarily in the context of online surveys. The SAPA method uses data collected from the administration of large inventories of personality assessment items to large pools of participants, though it differs from traditional data collection methods in that each participant responds to only a small subset of all available items.

Aperture synthesis

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 lobe-pattern of the interferometer produces an output which is one component of the Fourier transform of the spatial distribution of the brightness of the observed object. The image (or "map") of the source is produced from these measurements. Astronomical interferometers are commonly used for high-resolution optical, infrared, submillimetre and radio astronomy observations. For example, the Event Horizon Telescope project derived the first image of a black hole using aperture synthesis.
