| 摘 要： | 分析了机载激光水深测量系统中的深度反演方法，着重讨论波浪潮汐改正法和利用动态全球定位系统-相位模糊度解算技术(KGPS-OTF)所测参量进行归算的方法(无修正法)。综合分析影响机载激光测深精度的各项参量，并利用机载激光雷达的技术参数，定量估算了两种方法的水深提取精度。结果表明，波浪潮汐改正法的精度略高于无修正法，但是无修正方法更加简单明了，数据后处理的计算量也可大大减小。

| Abstract: | Depth retrieval method for airborne laser bathymetry is discussed. The corrected method using sea wave and tide and the non-corrected method using KGPS-OTF are introduced. The facts affecting the depth error in airborne laser bathymetry are analyzed. The depth retrieval errors of airborne laser bathymetry using the two methods are evaluated. The accuracy from the corrected method is little higher than that from the non-corrected method, while the non-corrected method is more simple and fast for data processing. |
