ЧТО ОЗНАЧАЕТ СЛОВО APERTURE SYNTHESIS
Синтез диафрагмы
Синтез диафрагмы или синтез изображений - это тип интерферометрии, который смешивает сигналы из набора телескопов, чтобы создавать изображения с таким же угловым разрешением, как и инструмент для всей коллекции. При каждом разделении и ориентации диаграмма направленности интерферометра дает выход, который является одной из составляющих преобразования Фурье пространственного распределения яркости наблюдаемого объекта. Из этих измерений получается изображение источника. Астрономические интерферометры обычно используются для оптических, инфракрасных, субмиллиметровых и радиоастрономических наблюдений высокого разрешения.
Значение слова aperture synthesis в словаре английский языка
Определение синтеза диафрагмы в словаре - это набор радиотелескопов, используемых в радиоастрономии, для имитации одного крупноапертурного телескопа. Некоторые из таких инструментов используют подвижные блюда, в то время как другие используют фиксированные блюда.

An Introduction to Radio Astronomy
An array of radio telescopes, their outputs separately amplified and combined
pairwise to form all possible interferometric combinations, is called an aperture-
synthesis array. In simple terms, the source is being observed with a collection of

The first radio-line observations were made with single dish instruments. In the
early 1970s aperture-synthesis telescopes started taking 21-cm data, while the
first aperture-synthesis observations in the mm band date from the late 1980s.
