| 摘 要： | 压差式矢量水听器不但能测量声场中质点的声压信息，同时也能测量质点的振速信息．这一特征使其能对声场中的目标进行方位估计。根据复声强定向原理对水下目标进行定位跟踪，试验结果表明，定住误差很小，效果良好。

| Abstract: | Pressure-gradient vector hydrohpone can measure the sound pressure and vector velocity of the particle in space. Because of this striking feature it can estimate the direction of the target in space. Direction-pursuing of the underwater target, according to the principle of complex sound intensity, is discussed in this paper. Experiments show that the error of direction is tiny and the effect is desirable. |
