摘    要:声相关计程仪是一种新型的测速声纳,其作用距离大,测量精度高,是理想的测速仪器;但是,空间相关计程仪并不是对任何时延都能测量出船只的航速。本文从理论上分析了造成这种现象的原因,找出了可以选取的时延的大致范围,并用计算机软件进行了仿真,最后通过实验得到了证明。

关 键 词:空间相关计程仪  声纳

Abstract:An acoustic correlation log with great operating depth and high measurement preci-sion is a new type of velocity determination sonar, and also it is a ideal velocity measurementapparatus; but spatial correlation log can not measure the velocity of ship for all tine-delay.Theoretical analysis was presented to explain the cause of the phenomenon, the availablescope of time-delay was obtained, and computed simulation was provided, finally it'sdemonstrated by experiment.
Keywords:spatial correlation log  precision of measured-velocity
