Abstract

Reduction of wave interaction errors in radio direction finding requires use of large aperture antenna systems. Application of the wide-aperture principle in the case of shipboard or aircraft antennas involves the construction of arrays around the various conducting surfaces of the ship or aircraft. The general methods of pattern synthesis described in this report by Dr. DuHamel will enable the antenna engineer to design arrays that will produce specified radiation patterns, using arrangements of antenna elements placed upon a circle, ellipse, elliptical cylinder, sphere, spheroid or ellipsoid; either with or without a concentric reflecting surface or some cases a method for obtaining an optimum design is indicated. In general, actual structures will only approximate the simple surfaces considered, and practical difficulties may preclude the use of the optimum design. Nevertheless, theoretical solutions for simple geometries as given herein can serve. as a guide to design in actual cases. Of course these methods of antenna pattern synthesis apply equally well in the case of acoustical radiators. A general method of pattern synthesis is presented for an array of antenna elements placed on a circle, an ellipse, a sphere, a spherical and an ellipsoid Since only the element pattern is required the antenna elements may be dipoles or loops, either with or without a concentric reflecting surface,· or slots This method of pattern syn­thesis could be quite useful in the design of antenna systems for direction finding, radar, and other applications.
