| 摘 要： | 激光测高仪是一种空间对地探测装置,在众多领域中有重要的应用前景.由于大气传输介质以及系统噪声的影响,需要对测得的数据做精确化处理.采用了抗差估计(IGGⅢ方案)来处理激光测高的数据,与最小二乘法相比,抗差估计既能减小模型偏差又能抗拒异常观测值干扰.

| Abstract: | Laser rangefinder is a tool for mapping earth. It has important application foreground in various fields. Because of the influences of atmosphere transmission medium and the system noises, it is required to process the measured values accurately.Compared with the least squares method, robust estimation (IGGIII project)is introduced which can resist both model error and abnormal values to deal with the laser rangefinder's measured values. |

| Keywords: | laser rangefinder least square fitting robust estimation IGGIII |
