摘要

Although intensive research work on automatic navigation and collision avoidance has been carried out,collision avoidance activities still depend heavily on human judgements,and radars are still most useful tool for collision avoidance at sea.In order to minimize human subjectivity and reduce human errors,it is of significance to properly process and display radar information to support human navigators in their decision making procedures.A suitable approach to support human navigators is to provide adequate information and its display for decision-making.In this papcr,a new approach of radar display is proposed.We define the range of course at risk (RCR) and the range of speed at risk (RSR) and display them on an outer ring of the radar screen and heading mark,respectively.A fuzzy method is employed for determining the radius of the guarding ring and a basic configuration of a fuzzy logic system for collision avoidance is proposed.We also propose two measures for estimating collision danger,the heading risk (HR) and the situational risk (SR).HR indicates the danger level of own ship's present course and speed,and SR indicates the general danger level of surrounding traffic.With our new display approach,the decision making becomes straight and no trial maneuver is needed.
