摘　　要：提出了顾及方向性的海底倾斜角解算模型。通过不同测线方向的数值仿真,验证了该模型的正确性,表明沿水深梯度方向布设测线可获得最接近于真实的海底倾斜角。The direction of beam width-effect has a significant influence in bathymetry. The slope angle of seabed is the key problem of the beam width-effect correction in bathymetry. Based on the theoretic analysis of beam-width effect, a slope angle calculation model was proposed, which consideres the direction of survey lines. The results of numeric simulation in different headings show that the model is valid and could get the most accurate slope angle when the survey line heading is the depth gradient direction.
