A Mills cross is a type of radio antenna that is used in radio astronomy to enhance the angular resolution of radio telescopes. It consists of two perpendicular linear arrays of dipole antennas, arranged in the shape of a cross. The design of the Mills cross allows for precise measurements of the direction of arrival of incoming radio signals.
History of Mills Cross
The Mills cross was first developed in the 1950s by radio astronomer Bernard Yarnton Mills. It was designed to overcome the limitations of single-dish radio telescopes, which have poor angular resolution due to their large collecting area. The Mills cross provided a cost-effective solution to improving the resolution of radio telescopes, making it easier to study celestial objects with greater detail.
Operating Principle
The operation of a Mills cross is based on interferometry, where the signals received by the two perpendicular arrays of antennas are combined to create interference patterns. By measuring the phase and amplitude of these patterns, astronomers can determine the precise direction from which the radio signals are coming. This allows for the construction of high-resolution images of the sky.
Applications of Mills Cross
The Mills cross has been used in a variety of radio astronomy projects, including mapping the structure of the Milky Way galaxy, studying pulsars, and detecting cosmic microwave background radiation. Its ability to enhance angular resolution makes it a valuable tool for astronomers looking to study faint and distant sources of radio emission.
Research conducted using Mills crosses has led to significant discoveries in the field of radio astronomy, helping astronomers better understand the nature of the universe and the objects within it. The technology continues to be used in modern radio telescopes and arrays, contributing to ongoing advancements in our knowledge of the cosmos.
Overall, the Mills cross remains an important instrument in radio astronomy, allowing astronomers to observe the universe in greater detail and unravel its mysteries. Its unique design and operational principles make it a valuable tool for studying a wide range of celestial phenomena, making significant contributions to our understanding of the cosmos.
