导标偏移量计算方法探研

Study of calculation method of off-axis distance of leading marks

导标偏移量是导标设计最基本参数,导标间距、高程、灵敏度计算都与它有关系。文章根据以往导标设计经验,结合航道设计、船舶在航道操纵和国际航标协会建议,分别进行导标偏移量计算,对计算结果进行对比论证,分析我国现行导标设计规范在计算导标设计偏移量中存在的问题,说明我国导标设计规范的修订具有现实需要。通过论证,文中针对导标偏移量计算思路和方法提出新的建议,为更加完善的导标设计方案提出解决方向。

Off-axis distance of leading marks is the most basic data of leading mark design. It is the key parameter in calculation of leading marks distance, mark＇s elevation and sensitivity. Based on the existing rules, the problems of off-axis distance calculation of leading marks were discussed according to the experience of leading marks design, including channel design and vessel operation in channel. It means that the revision of existing lead- ing marks rule is the demand of reality. A new recommendation about method of leading marks off-axis distance cal- culation was also put forward in this paper.
