摘要
声相关计程仪是利用相关技术获得载体航速和航程的导航仪器。在目前声相关测速文献的基础上,描述了声相关测速的基本原理,结合不同工作条件下的发射信号形式,对时间相关、空间相关和基于模型匹配的信号处理方法等相关测速技术进行阐述,最后对测速技术进行了展望,并给出了相关结论。
Acoustic correlation log is the navigation instrument that can acquire the carrier velocity and range by correlation technique. Based on some literatures about acoustic correlation velocity measurement, this paper describes the basic principle of acoustic correlation velocity measurement, expatiates the acoustic correlation velocity measurement techniques such as temporal correlation, spatial correlation and signal processing method based on model match, etc. , finally prospects the velocity measurement techniques and gives out the related conclusions.
