基于扰动压力与速度测量水中目标航向与航速的新方法

摘要

A new method of measuring underwater target heading and speed based on its pressure and velocity disturbances is presented by the relative of the disturbances pressure and velocity of the underwater vehicle at a point in water from Bernoulli equation for incompressible steady frictionless streamline flow. The experiment of the ship model shows that the method can well and truly measure the underwater vehicle heading and speed, the error of the ship model's heading and speed is less than 5% and 20%. It shows the perspective of practical application in the future.%从不可压理想定常流动的伯努利方程出发,依据水中航行体对水中某点的扰动压力与扰动速度的相关性,提出了基于水中航行体对水中一点的扰动压力与扰动速度测量该航行体的航行速度与航向的新方法.船模实验表明,该方法能较准确地测量出水中航行体的航向与运动速度,航向测量误差在5％以内,速度测量误差在20％以内,说明该方法具有实际应用前景.
