| 摘 要： | 多线阵可解决单线阵在目标探测中的左右舷分辨模糊问题,但阵形畸变不利于准确实现对目标的左右舷分辨。本文针对多线阵在拖曳过程中出现的典型阵形畸变,定量地分析了其对目标左右舷分辨的影响,并提出了一种基于阵形畸变实时测量补偿来进行目标左右舷分辨的方法,海上实验数据分析结果表明,该方法可实现阵形畸变下的目标左右舷分辨,对于提高拖曳多线阵声纳性能具有参考价值。

| Abstract: | The port/ starboard discrimination can hardly be carried out with single-line array.Multi-line array can be used to solve the problem.However the shape distortion degrades the performance.In this paper,the effect of the array distortion on the port/starboard discrimination of towed multi-line array is analyzed.Then,a real-time compensation method of array shape distortion is brought forward.Finally,sea trial data verifies the effectiveness of this method. |
