Implications for microwave radio path design of the evaporation duct over tropical oceans in northern Australia

Abstract

Examples of evaporation duct height statistics for coastal and oceanic waters in the North of Australia are presented. The range in duct height variation measured in coastal waters beckons further investigation of the effects of the evaporation duct on fixed link performance. Fixed link design issues are addressed in the context of the tropical evaporation duct and a suggestion made so that designers may avoid interference problems resulting from anomalous propagation inside the duct.
