The synthesis of antenna arrays is a very long standing field in electromagnetism because of its many applications (e.g. radar, radio astronomy, sonar, communications, direction-finding, seismology, medical diagnosis and treatment). A host of methods have been proposed since the 40's to solve increasingly difficult synthesis problems. These techniques range from analytical methods (fast but limited to very specific problems) to global optimization approaches (comprehensive but limited in performances due to their computational burden). Convex optimization has been shown to be a good trade-off in efficiency/generality between analytical and global optimization techniques. The purpose of the talk is to show that a variety of difficult antenna array synthesis problems can be relaxed as convex optimization problems and therefore efficiently solved. The synthesis of shape beams and reconfigurable arrays by phase-only control will be addressed.
