抗差估计在无验潮单波束测深异常数据检测中的应用

Application of Robust Estimation to Detecting Abnormal Data of Single Beam Sounding Without Tide Test

针对水下地形测量存在的异常水深值问题,该文研究了一种基于水深数据链高崩溃抗差估计的滤波方法,并以计算机仿真实验数据与实测水深数据来验证此方法。实验表明,该方法能够快速有效地检测异常值的位置,以测深数据的地形性来弥补抗差估计经验值的主观性。

Aiming at the problem of abnormal depth of water in underwater topographic survey,a filtering method based on robust estimation of water depth data chain with high collapse is studied in this paper.The computer simulation data and measured depth data are used to verify this method.The experiment shows that the method can detect the location of abnormal value quickly,and effectively.The topo-graphic nature of sounding data is used to make up the subjectivity of the empirical value of robust estimation.
