| 摘 要： | 建立了海面浮油探测荧光激光雷达的系统模型,根据浮油探测的特点,给出了荧光激光雷达回波信号方程.以此方程为基础,结合石油的消光系数及荧光光谱转换效率数据,对模型的回波信号强度进行仿真,得到了该模型探测不同类型石油时的荧光回波光子数.为进一步计算该模型的信噪比,分析了海洋浮油探测背景噪声的特点,得到海水黄色物质产生的背景噪声.通过信噪比公式计算了荧光激光雷达模型的信噪比,计算结果表明,该系统模型能够满足机载海面浮油探测要求.

| Abstract: | The model of fluorescence lidar system for detecting marine oil was proposed and the fluorescence lidar equation was deduced. Based on the equation, the backscattering fluorescence signal from marine oil could be calculated. During the process of calculation, the oil extinction coefficient and fluorescence spectra conversion efficiency were introduced in the lidar equation. In order to obtain the SNR of lidar model, the special feature of background noise around marine oil was analyzed and the noise signal from yellow substance (CDOM) was calculated. As a result, the system SNR could be simulated. Simulation results indicate that hypothetical fluorescence lidar model could meet the demands for airborne detecting marine oil. |
