摘要
根据辐射传输理论,研究了目标背景对比度的传输过程,分析了目标背景对比度在海水、海-气界面及大气中的传输特性,探索了可见光下目标的视觉检测条件,建立了可见光隐蔽深度模型。利用卫星资料反演的水体的光衰减系数、浊度和透明度等遥感产品,建立适用于大范围海区的光学隐蔽深度定量遥感模式。测量了透明度盘、模型在不同站点的光谱特性和可见深度,并对可见光隐蔽深度模型进行了实验验证。数据表明,实测数据与理论计算的相对误差小于20%,研究结果对水下可见光隐蔽深度方面军事应用和可见光隐蔽深度遥感获取可靠性研究具有重要意义。
According to the radiation transmission theory,this paper studies the transmission process of target background contrast ratio,analyzes the transmission characteristics of target background contrast ratio in seawater,sea-air interface and atmosphere,explores the visual detection condition of targets under visible light,and establishes the visible light hidden depth model.Using remote sensing products such as light attenuation coefficient,turbidity and transparency of water body retrieved from satellite data,a quantitative remote sensing model of optical concealment depth suitable for large-scale sea area is established.The spectral characteristics and visible depth of the transparent disk and model in different stations are measured,and the visible light hidden depth model is experimentally verified.The data show that the relative error between the measured data and theoretical calculation is less than 20%.The research results are of great significance to the military application of underwater visible light concealment depth and the reliability research of visible light concealment depth remote sensing acquisition.
