雷达避碰中误差理论的应用

Application of Error Theory in Collision Avoidance with Radar

本文运用误差理论对用雷达标绘法求解来船航向航速的准确性进行了定量分析。在分析的基础上给出了一种新的绘算避让航向的方法。使用该方法能保证以95％以上的概率安全地避让来船于预定的 minCPA 以外,并且使转向角度最小。

On the basis of error theory,this paper makes a quantitative analysis of the course and speed of the target gained by radar plotting solution.Then it presents a new method of plotting ownship's avoidance course on the base of the above analy- sis.This new method ensures that the ownship,at a probability of more than 95％,avoid the target safely with CPA≥the set minCPA,and make a minimum course alternation.
