水下目标光学隐蔽参数测量技术在光学侦察、探测水下目标等军事运用中发挥了非常重要的作用。为了改变以往使用透明度盘测量海洋光学参数方式,提高测量的效率和测量结果精准度,在分析水下目标光学隐蔽参数的基础上,设计了船载水下目标光学隐蔽参数测量方法,利用lightools软件优化光学探头设计,采用无线方式实时传输海水光学参数数据,并进行了海上实验,测量得到了海水辐照比、海水体衰减系数和漫衰减系数,完成水下目标光学隐蔽参数分析,实验证明了该测量方法的可行性和可靠性。

The techniques of measuring the optical concealed parameters of underwater targets play a very important role in optical reconnaissance, underwater target detection and other military applications. In order to measure the optical concealment parameters of underwater targets on ship and improve the efficiency and precision of measurement, this paper designs a shipboard concealed optical parameter measuring system based on the analysis of optical converting parameters of underwater targets. Using the Lightools software to achieve the optimal design of the optical probe, the design adopts the method of wireless real-time transmission of seawater optical parameter data, with experiments completed in real sea state. It also measures the radiation ratio, the volume attenuation coefficient and the diffuse attenuation coefficient of the sea. The analysis on the optical concealment parameters of underwater targets is completed through experiments, which proves the feasibility and reliability of the presented measurement method.
