| 英文摘要 | Multibeam echosounder system (MBES) is an essential acoustic remote sensing technique for seabed topography surveys. The georeferenced model is crucial for the MBES when calculating the bathymetric soundings' geolocation and depth. Existing models are complex and time-consuming, failing to meet the demands of large-scale or real-time data processing. To address these issues, we proposed a simplified and high-precision method. First, two regular sectors with the same vertex are assumed to represent the across-track and along-track beam patterns of the multibeam transmitter and receiver, respectively, instead of two cones in the conventional virtual concentric cone array (VCCA) model. Secondly, the beam vector representing the direction of sound ray tracing is derived by calculating the intersection point coordinates between the two sectors. Finally, an efficient progressive equivalent sound speed profile ray tracing progress is used to obtain the final depth of soundings. Experimental results demonstrate that the proposed method substantially reduces processing time, with reductions of approximately 52% for shallow water data and 84% for deep water data. The root mean square error of depth discrepancies is approximately 0.58% of water depth in overlapping regions of cross-survey lines. Furthermore, the proposed method achieves accuracy comparable to the VCCA algorithm. |
