摘要

初始的光学隐蔽深度模型(OCD)是在海水光学性质均匀的条件下建立的，针对光学性质均匀水体假定条件下的光学隐蔽深度模型缺乏普适性的缺点，基于海水中对比度传输方程，在垂向方向上把海水划分为多个光学性质相似的均匀层，并依此建立非均匀海水条件下光学隐蔽深度(OCD_LAYER)模型。计算并分析了观测天顶角、海水体衰减系数和潜器表面反射率对非均匀海水条件下光学隐蔽深度模型的影响。使用潜模和光学隐蔽深度测量系统在近岸完成模型的实验验证和效果分析。使用3 m水柱漫衰减系数均值，OCD模型的平均均方根误差为1.19 m，平均绝对误差为1.19 m，平均相对误差为48.77%，OCD_LAYER模型的平均均方根误差为1.05 m，平均绝对误差为0.89 m，平均相对误差为36.18%。实验结果表明，OCD_LAYER模型准确性更高，误差更低，结果更可靠。

Abstract

The initial model of optical concealed depth (OCD) was established under the assumption of uniform optical properties of seawater, which had limited applications. Nonetheless, we developed a new model that views seawater as a non-uniform layered entity. Based on the contrast transfer equation, seawater was divided vertically into different areas, and each vertical division had multiple properties similar to the properties of homogeneous water. Subsequently, the new model of optical concealment depth for layered water(OCD_LAYER)was established. The observation zenith angle, attenuation coefficient of seawater, and surface reflectance of submarines were calculated and analyzed accordingly. The verification test and the effect analysis of the model were performed based on the latent model and measurement systems. As a result, the mean value of the diffusion attenuation coefficient is found to be 3 m. In the OCD model, the average root mean square error is 1.19 m, the average absolute error is 1.19 m, and the average relative error is 48.77%. Meanwhile, the OCD_LAYER model displays a better estimation system, as indicates by lower errors; the average root mean square error is 1.05 m, the average absolute error is 0.89 m, and the average relative error is 36.18%. The experimental results show that the proposed model demonstrates higher accuracy and provides more reliable results than the initial model.
