Radar Tracking and Plotting Equipment

Abstract

The plotting by the use of Radar is essential to collision avoidance as its practice has been adviced by IMCO. "Radar Tracking and Plotting Equipment" which plots automaticaly by means of electronics has bee successfly developed. This equipment consists of data proccessor and IC memories. Using conventional shipborne radar, it is able to plot five points of the passed track of a target ship automaticaly on the radar plan position indicator. Farthermore, it is able to choose the most safty maneuvering by the use of trial maneuvering computer system when the risk of collision was found. This paper describes the design and principle of this equipment, and also the experimental result that has been obtained on board for these one and a half year. On the basis of this result, they concluded that plotting is available under rough sea condition and heavy sea clutter. It was also concluded that the principle of trial maneuvering has been established with this equipment although this has a few mechanical week points.
