VHF ON-SHORE DIRECTION FINDERS FOR CONTROLLING MARINE TRAFFIC
Sea traffic expands continually, especially in coastal areas, and connected problems of traffic surveillance and control increase accordingly. European concentrations of sea traffic occur in the English Channel, the mouth of Rhine/Schelde, the Europort at Rotterdam, and in the German Bight. Beside many classical instruments for traffic control in the maritime field the use of coastal direction-finding systems has become increasingly important. The classical direction-finder has found a new role in supporting radar surveillance through a VHF telephone link with ships. The main functions of the direction-finding system are for instance the identification of ships travelling in a convoy, by making visible the df beam on the radar screen, and the determination of position by means of automatic computer-operated split direction-finding. The usefulness of the concept will be demonstrated by practical experiments carried out on the French Channel coast. The aim is to develop a highly precise coast-direction-finder with increased range. Further possibilities in the maritime field are seen in the use of df systems on platforms and ships where helicopter traffic has to be controlled.
