| 中文摘要 | 讨论了机载激光海洋测深技术中采用红外激光测量海表的精度和探测概率。首先介绍了机载激光测深系统中红外激光测距的原理以及计算方法；分析了不同扫描角、海况(尤其是不同风速)下斜距的测量方法、测量精度及对回波信噪比的影响，分析了在给定探测概率下甄别闽值的选择以及探测概率和信噪比的关系。最后用机载激光测深系统的参数对海表探测进行了数值模拟和讨论，提出了改进措施。 |
| 英文摘要 | The accuracy of measurement and detection probability of the sea surface using infrared laser in airborne laser bathymetry are discussed. The principle and analysis of the distance detection using infrared laser are introduced, and the accuracy of the inclined range at different scanning angles and different status of the sea, especially at different wind speed, is evaluated. Then the selection of discrimination threshold and the relationship between detection probability and SNR with giving criteria of detection probability are analyzed. Based on the simulation and parameters of the airborne laser bathymetry system, some improved methods of accurate measurement of inclined range are proposed. |
