| Abstract: | In this paper,the effect of sounding anisotropy during the course of depth interpolating is discussed.Then a method for depth interpolating based on spatial structure of sounding field is proposed.Experimental results demonstrate that the proposed method saves more terrain information and also improves the quality and the stability of interpolating result. |
