Abstract
The accuracy of bearing measurements by direction finding systems is no longer limited by system sensitivities. It is however limited by geographical effects of the surrounding terrain, which result in multipath conditions and bias error in the bearing measurements. The polarization of a propagating electromagnetic wave is uniquely affected by it's reflection off the inter-lying terrain. by measuring the received signal's polarization and respective bearing direction, and accounting for terrain variations; theoretical analysis, using the inverse scattering technique, provides an indication of the bearing offset. The Dual H-Adcock Antenna is a novel design which has been constructed and characterized. It provides measurement of the polarization and direction of arrival of the received signal by means of measuring the vertically and horizontally polarized signal components separately. TRUNCATED
