THE HAMBURG HARBOR SHORE-BASED RADAR CHAIN. AN INSTRUMENT FOR TRAFFIC CONTROL

From the point of operation it is essential that a permanent crew is required only in one station the so- called Central Radar Station, all the other stations being unattended and remotely controlled. This scheme calls for a Telecommunication link between the unattended stations and the central station to bring the video-information from the unattended stations to the central station. You can do this on two ways: by radio link or by cable. The displays in the Central Radar Station show the unchanging picture of an essential part of the harbor with only the ship-targets moving on the screen. Thus the Radaroperators at all time have a good general idea of the traffic-situation in this region and therefore they can inform the ships under control not only of their exact position but also of the traffic in their vicinity. Experience has shown that this additional information which the ship cannot get by her own means is at least of the same importance as the knowledge of her own position, and this is one of the reasons why in practical operation the shore-based radar chain works 24 hours a day even in full sunshine and not only in bad visibility! The possibility of a permanent supervision of the traffic in the harbor is of high value to the port management, too. In order to avoid any misunder- standing about the term Traffic Control, I would like to emphasize that the responsibility for the ship continues to lie without any restrictions with the Master of the ship, who will be assisted by the pilot. The Master can receive all information which the Central Radar Station can give about the position of his ship and the general situation of the traffic, and it is he who ultimately has to decide what to do.
