水下航行器光学隐蔽深度测量系统

Measurement system for optical concealment depth of underwater vehicle

为了实现对水下航行器光学隐蔽深度的实时测量,研制了水下航行器光学隐蔽深度测量系统。根据目标背景对比度的传输理论,分析了目标背景对比度在海水、大气、海面的传输特性,建立了水下航行器光学隐蔽深度模型。基于该模型分析了测量水下航行器光学隐蔽深度所需要的参数,设计了测量海水上行辐照度、海水下行辐照度、海水体衰减性系数、海水漫衰减性系数和水下航行器表面反射率的测量方法,并完成一次海上试验。试验测得良好天气情况下特征尺度为12m的水下航行器的光学隐蔽深度为25-35m。试验结果表明,设计的测量系统可以实现对水下航行器光学隐蔽深度测量,并适用于各类潜艇。由于改变了传统的在水面进行深度测量的方式,该系统工作稳定可靠,提高了隐蔽性和对海域测量的准度,可为水下作战决策提供帮助。

To realize the real-time measurement of optical concealment depth for a vehicle under water,an optical concealment depth measurement system for the underwater vehicle was developed.According to the target background contrast transfer theory,the transport properties of the target background contrast in sea water,air and sea were analyzed and a model of underwater optical concealment depth for the vehicle was established.On the basis of the model,required parameters for measuring optical concealment depth of underwater vehicle were analyzed and the measuring methods for the water upward irradiance,water downward irradiance,water body attenuation coefficients,water diffuse attenuation coefficients and underwater vehicle surface reflectivity were designed.Then,an experiment on sea was completed,and it shows that underwater optical concealment depth of the vehiclewith a characteristic scale of 12 mranges from 25 mto 35munder good weather conditions.The experimental results indicate that the measurement system successfully measures the depth of optical concealment of the vehicle and also is suitable for other submarines.As it avoids the traditional depth measurement mode,the system has stable and reliable operation,improves the conceal ability and measuring accuracy,and provides the supports for underwater flight decision.
