ANALYSIS OF THE SPIRAL ANTENNA DIRECTION FINDER

Abstract

A study was made of a method previously suggested for constructing a passive direction finder capable of determining the azimuth and elevation of an electromagnetic wavefront. This direction finder consists of a two-wire, Archimedian, spiral antenna and a phase comparator. Angular information of accuracy too low for the intended application is obtained when the theory and experimental data previously presented are used. A general theory for the direction finder is established and methods for accuracy improvement are suggested.
