Phased array
| Глоссарий по неразрушающему контролю в авиации |
- In ultrasonic testing, a phased array is a mosaic of transducer elements in which the timing of the elements’ excitation can be individually controlled to produce certain desired effects, such as steering or focusing the beam.
- Mosaic of transducer elements in which the timing of the elements’ excitation can be individually controlled to produce certain desired effects, such as steering or focusing the beam.

Array, английский
- A block of multiple images arranged in columns and rows.
- The order of battle.—to array. to equip, dress, or arm for battle.
- Two or more components feeding a common system (e.g., hydrophones for sonar, antennae for radar).
- An indexed and ordered collection of objects (i.e., a list with indices). the index can either be numeric (o, 1, 2, 3, ...) or symbolic (`mary`, `mike`, `murray`, ...). the latter is often referred to as "associative arrays."
- See photovoltaic (pv) array.
- Group of sensors arranged to locate signal sources, to expedite scanning, or to acquire signals whose excitation is phased in its timing.
- Группа датчиков, предназначенных для обнаружения источников сигналов, ускорения сканирования или получения сигналов, возбуждение которых поэтапно по времени.
