本文讨论了超声波回声测深仪测深误差的改正。笔者将测深误差的改正归纳成两大类五种。第一类系仪器设计参数与实际情况不符所引起的测深误差改正,计三种;第二类系仪器的结构和安装所引起的测深误差改正,计二种。本文所讨论的测深误差改正的原理和方法,对于使用声波进行物理量量测的有关水声仪器,如海底地层剖面仪、海底地貌仪、多波束测深系统等,均具有一定的参考价值。限于篇幅,文中公式推导从简或从略。
This article discusses the correction of sounding errors of ultrasonic echo sounder. The author summarizes the correction of sounding errors into two categories and five. The first type of instrument design parameters and the actual situation caused by the sounding error correction, in three; the second type of instrument structure and installation of the sounding error correction, two. The principles and methods of correction of sounding errors discussed in this paper have some reference value for underwater acoustic instruments such as submarine stratigraphy, submarine geomorphology and multi-beam sounding systems that use sound waves to measure physical quantities. Due to space limitations, the article derived from the simple formula or omitted.
