N2  - Pulse radar systems act as the eyes of a ship during periods of reduced visibility and are thus one of the most important navigational aids. Increasingly, information obtained from radar is now processed by computers to create an automatic, anti-collision device (Automatic Radar Plotting Aid - ARPA) to give advance warning of potential navigation risk. Employing a systems approach to the subject, this companion volume to Position Fixing provides an explanation of the workings and application of both pulse radar and ARPA systems in the marine environment
