基于动态水位的涉水距离和深度计算方法

A method for computing wading distance and depth based on instantaneous water level

涉水距离和深度计算是登陆决策分析中的重要内容。针对传统方法的不足,本文提出了一种基于动态水位的涉水距离和深度的计算方法。根据瞬时水位,动态地求定实时水线和登陆点之间的坡度,从而可动态地得到涉水距离和深度。实验证明,此方法与传统方法相比,所计算的涉水距离和深度在准确性上有明显提高。

The computation of distance and depth plays an important role in landing decision. Aiming at the drawbacks of traditional methods, this paper presents a method for computing wading distance and depth based on instantaneous water levels. The slope between instantaneous waterline and landing point is computed considering changing water level, and wading distance and depth are obtained dynamically. Experimental result shows that the proposed method is more accurate than the traditional one in computations of wading distance and depth.
