摘    要:多波束在测深的同时也记录回波强度数据。在分析多波束回波强度记录方式的基础上,主要针对波束内回波强度的定位和数据优化等问题进行了探讨,确定了回波强度位置归算方法。最后,以Simrad EM1002多波束实测的回波强度数据为例,进一步阐述了在地理坐标框架下回波强度的图像化表示方法。

关 键 词:多波束测深系统  回波强度  位置归算  图像化表示

Abstract:Multibeam echo sounder(MBES) records bathymetry and echo intensity data simultaneously.Based on analysis of the ways of echo intensity's record of MBES,this paper focuses on localization of echo intensity in each beam and optimization of sample data in each ping,and presents the method of echo intensity position reduction.Finally,with the example of real measured echo intensity data of Simrad EM1002 MBES,the formation of sonar mosaic in geographical coordinate is elaborated.
Keywords:multibeam bathymetric system  echo intensity  position reduction  image denotation
