| Abstract: | The CUBE algorithm in automatic processing multibeam bathymetry data is introduced in detail by its model construction, multiple estimations of grid node and the rules of selecting best available estimation. The efficiency of multiple estimations is analyzed intensively, and the algorithm is implemented using multibeam real data. The Robust Kalman filter is presented to improve the CUBE algorithm. The improvement of the algorithm is compared by the experiment of synthetic data, and its necessity is showed |
