摘要
简要的介绍了基于统计特性进行多波束测深数据滤波的方法,并对这些滤波方法的特点及实际应用效果进行了对比分析,在此基础上,提出了趋势面滤波法,并对其进行了实践验证,取得了理想的效果。
In this paper, some traditional methods used for the filter of MBS sounding data, which are based on statistic analysis, are introduced and discussed firstly. By comparing and analyzing, we found the shortcomings of these traditional methods in practical applications. In order to get ideal filtering result, a new method, which is trend surface filter, is presented in this paper. The theory of the new method is depicted in detail. Some applications and analysis are also shown in the paper. Ideal filtering results achieved in actual applications show that the new method is credible.
