The heart of the Satellite-Aided Collision Avoidance concept is a shipboard radar processor which compresses typical search radar video bandwith (7 MHz) into a teletype data rate, while retaining all essential target information. This radar processor has been implemented using shore-based interactive control and simple, inexpensive onboard digital logic; such that the need for an expensive shipboard computer is eliminated. The use of shore-based automated collision avoidance processing offers the potential advantages of reliability (distributed hardware), lower cost (time-shared computer), more effective threat evaluation and maneuver advisories (greater processing power) and improved safety (third-party expert overview). This paper presents a description of the concept and the experimental hardware and software which was evaluated at Kings Point, Long Island. Typical test results are also summarized.
