| Abstract: | A synthetical correction method of depth survey - multiple measuring line correction is proposed. The coupling effect of angular beamwidth with topography and vehicle attitude is analyzed. Furthermore, the digital fathometer is designed in detail and correction index is constructed. Then, a real seabottom terrain is used to verify the method. Simulation shows that this method has obvious correction effect to solve the seabed distortion. |
| Keywords: | sounding multiple measuring line correction topography coordinate effect of angular beamwidth |
