Resulting from researches and experience accumulated in mbss practice for years , the author suggested a precision estimation model of depth and position for the acceptance of mbss systems , and presented further a stochastic model of double observation for data quality estimation . these models could be introduced to the designed national mbss acceptance standards
本文根据国际海道测量标准提出了多波束测深系统的水深和位置精度的评估模型，并提出了一种双观测法统计模型对测量数据的质量进行评估，其研究成果可以为建立我国多波束测深规范提供参考。
