A Compact Array is a type of antenna configuration used in radio astronomy and telecommunications. It consists of multiple antennas placed close together, allowing for efficient data collection and improved signal quality. This arrangement helps in capturing detailed information from celestial objects or enhancing communication signals. The design of a Compact Array enables the combination of signals from different antennas, which can create a more precise image or clearer transmission. This technique is often employed in facilities like the Very Large Array in New Mexico, where it aids in studying astronomical phenomena and improving communication technologies.
