The speed of approach measuring instrument (SAMI) radar berthing system is described. The capabilities of the original SAMI equipment were limited to measuring the speed of ships as they approached the berth. A major limitation of the first SAMI was that it gave the velocity of the ship at one point only. This is insufficient when a ship is moving laterally through the water, since the bow and stern can have different velocities with respect to the berth. Another inability of the original system was its incapability to identify the direction of movement. The present SAMI system gives a full coverage of bow and stern velocities and direction information, as well as the distance of the ship from the berth. The major elements of the present system include the RF head unit and the processing and display unit, both of which are briefly described. The operation of the system as well as variations which can be made to accommodate a particular port area are also discussed.
