Abstract
A circular array antenna is highly attractive for direction finding (DF) because of its geometrically circular symmetry and the periodicity of its electromagnetic features, such as mutual coupling between elements of the array, when its beam is scanned electronically through 360 deg. in azimuth. The element voltage response to an incident plane wave of a circular array are used as inputs for the DF signal processing studies. In Part I of this report, the effects on the element response of the mutual coupling in the circular array, lossy ground, the polarization and elevation angle of incident wave are studied. An efficient software for the element response of a circular array of dipoles has been developed. In the Part II of this report, the DF algorithms used are based on the MUSIC and on the maximum likelihood methods. TRUNCATED
