船底气泡对声学计程仪的影响研究

Research on the Influence of Bottom Bubbles on Acoustic Log

从国外军、民领域计程仪的发展历程来看,声学计程仪是未来的主要发展方向。而声学计程仪因测速原理的固有特性,容易受到船底气泡的影响,导致测速功能异常。论文阐述了计程仪的发展历程、声学计程仪的测速原理以及针对气泡问题在实船上开展的试验结果和数据分析,为声学计程仪解决气泡问题提供了一种思路。

From the perspective of the development of foreign military and civil log,acoustic log is the main development di-rection in the future.Because of the inherent characteristics of the speed measuring principle,the acoustic log is easily affected by the bubbles at the bottom of the ship,resulting in abnormal speed measuring function.This paper describes the history of the devel-opment of the log,the principle of acoustic log speed measurement,and the test results and data analysis carried out on a real ship to solve the bubble problem.It provides an idea for acoustic log to solve the bubble problem.
