针对目前广泛使用的经验取浅方法在安全可靠性上的不足,提出一种基于不确定度的水深控浅方法。所提方法计算原始观测和内插水深的不确定度信息,并基于不确定度信息设计安全可靠的水深控浅模型,比对分析两种水深表达方法的保证率。试验证明:与经验取浅方法相比,所提方法可明显提高水深模型的保证率,特别是在水深变化复杂的区域。%Aiming at the shortage of a common experimental shoal-biased method assuring navigation safe,a method for controlling shoal-bias based on uncertainty is proposed.Uncertainties of raw depth and interpolated depths are calculated,a safe and reliable model for controlling shoal-bias based on depth uncertainty is designed,and the assuring rate of two depth models for safe navigation are compared and analyzed.Experimental results demonstrate: the proposed method have higher assuring rate than that of the experimental shoal-biased binning method,especially in areas where depths change complexly.
