High resolution antenna arrays with randomly spaced elements

Large phased arrays have received great attention in recent years as the high resolution antennas become in increasing demand. More recently the Advisory Panel of Radio Telescopes of the National Science Foundation[1] has adopted the resolutions on the need of a decimeter radio telescope with a 1´ of arc beam. A preliminary study for the Benelux project[2] also considered a few antenna arrays for Mills-Cross type telescope. Motivated by such activities the present investigation was made in an attempt to develop a new technique in the design of high resolution antenna arrays.
