Outline of Final Research Achievements

To make a radio telescope work effectively, it is necessary to measure and adjust the surface of its mirrors so that they are in ideal shape. Since next-generation radio telescopes are to have larger dishes, higher target frequencies, and wider field of view, development of mirror surface measurement is needed. This study is aim to verify the principle of a new method which measures wave phase on the focal plane, and assembled a small radio interferometer. Theoretical research was also made and some results in antenna theory ware obtained.
