Such developments would demand extensive revision of IMO and other regulations, not only those relating to radar itself, but extending to SARTs, racons, RTEs and reflectors. If only for that reason, new concepts will not supersede conventional technology for at least a decade and equipment to the current concept will surely be around in a quarter of a century's time. The underlying laws of physics are eternal and well understood, so most of the content of this book will always remain valid, come what may.

Hardware meant screws. Software? What have woolly jumpers to do with radar? The term did not exist. Detail design by pencil, paper and sliderule was laborious and of variable quality, necessitating much 'cut and try' prototype testing. In 1977, after a spate of accidents causing pollution, political pressure caused the United States Coast Guard to issue, after discussion, regulations requiring all ships entering US waters to carry and use a collision avoidance system, to include continuous evaluation of the echoes of all ships posing a collision risk.

Moves are afoot in IMO to introduce long range identification and tracking of ships by AIS for security purposes, which may necessitate some form of integration with VTS radar displays. An increasing number of systems akin to VTS are being installed to monitor shipping movements within traffic separation schemes (TSS) for safety purposes. 3 shows a typical tower-mounted scanner. At the other end of the scale, coastal surveillance radars are used by coastguard and voluntary organisations to keep a safety watch on inshore craft near popular leisure resorts, particularly where currents can so often cause problems to the inexperienced, see Figure \A(a)-(c).
