Radio Interferometer
A gigantic radio telescope ALMA produces images of target objects by combining observation results obtained with 66 or more antennas spread over a wide area. Like ALMA, a radio telescope consisting of multiple antennas that receives radio waves from the same astronomical object is called “radio interferometer.” Here, you can learn how the radio interferometer works and why so many antennas are needed for the observation with an interferometer.
