| 摘 要： | 宽带声学多普勒流速剖面仪,由于其具有很高的空间分辨率和时间分辨率,所以在水文、运输、测控等方面都有很广泛的应用,而其最大作用距离对于其应用范围具有重要意义。根据主动声纳方程各项的意义,分析了深度单元厚度、温度和频率等条件因素对宽带声学多普勒流速剖面仪作用距离的影响,从而对宽带声学多普勒流速剖面仪的最大作用距离进行估计,得到理论计算值。将理论计算值与RDI公司的宽带声学多普勒流速剖面仪作用距离进行比较,作用距离范围吻合性很好。对BBADCP以及具有相同工作原理的声相关计程仪、多普勒计程仪和NBADCP进行对比分析,指出它们在作用距离上的区别。

| Abstract: | Due to the high spatial and time resolution,Broadband Acoustic Doppler Current Profile（BBADCP） has a comprehensive application in hydrology,transportation,measurement controlling etc.The maximum working range is significant for the application.According to Active sonar equation,the influence of depth cell size、temperature and frequency on the working range of BBADCP is analyzed.The theoretical calculation of the maximum working range of BBADCP is made.Comparing the calculated results with the datasheet of RDI BBADCP shows that the working ranges are identical.In addition,the differences of working range between Acoustic Correlation Log、Doppler Velocity Log、 Narrowband ADCP and Broadband ADCP are also compared. |
