A Survey of Five Years' Progress in Marine Radar

Abstract

In describing progress in the development of a functional equipment, it would be quite normal to begin by defining the technical targets at which the engineers are aiming and the operational uses to which it will be put. In the case of marine radar, however, it is not possible to be precise in either of these matters. It might be said that the ultimate target is to make port, coastal and open sea work as safe and straightforward in poor visibility as in good; or, put in another way, to replace direct human vision in poor visibility and to improve upon it at any time when the distance of targets is to be measured with accuracy.
