Abstract

In certain naval and coast guard security operations a video must be transmitted from an aerial platform - aircraft, helicopter, unmanned aerial vehicle or airship - to a surface station in real time. In this paper the radio channel characteristics and the antenna systems needed are examined in order to achieve a robust direct communication channel with enough bandwidth between the airborne vehicle and the base station. Simulation and experimental work has shown that for a reliable operation, diversity (spatial or frequency) techniques must be used in order to achieve the most reliable link between a moving and a stationary platform over any terrain, and any troposphere conditions.
