Radar has proved itself to be of great value as an aid to avoiding collision in low visibility, but the advantages are not so much useful in close-quarter situation, as to find dangerous circumstances to be avoided in the early stage. From this point of view, the only safe and accurate way of getting the necessary information for early avoidance by radar observation is to plot the movement of targets. We are convinced of RADAR PLOTTER shown in this paper, a device for plotting without using drawing instruments, being one of most convenient and effective plotting aid.
