摘　　要：针对多波束测深系统换能器安装过程中存在角度偏差问题,给出了换能器安装偏差的相关定义,建立了换能器横向、纵向及艏向安装偏差影响模型,阐述了各项安装偏差对海底地形测量的影响机理,结合算例,研究了各波束点水深误差与位置误差随波束指向角的变化规律及影响量级,进一步给出了部分代表性波束点水深偏差及位置偏差随安装偏差角的变化规律及影响量级,最后分析了各安装偏差间的相关性,以期为换能器安装偏差校正及测深数据质量控制提供一定的参考。For the transducer angle installation offsets in the multibeam echosounder system, the paper defined the transducer installation offset,built the effect models of the transducer＇s roll, pitch and yaw installation offsets and expounded how each installation offset affected the seafloor topographic survey, for example, how the depth error and position error of each beam changed with the beam angle and the influence order were researched, moreover, how the depth error and position error of some typical beams changed with the installation offsets and the influence order were also researched, and finally, the relativity of transducer installation offsets was analyzed, and the paper was expected to provide reference for transducer installation offset calibration and bathymetry data quality control.
