相关法是水声基阵测向测距的常用方法。比较分析了线阵分裂波束相关与直接相关法的测向性能。实测船噪声仿真研究表明,在低信噪比下,分裂波束相关性能较好;但随着信噪比的升高,两者性能接近。
The correlation method is a commonly used method for underwater acoustic array ranging measurement. The performance of line-direction splitting beam correlation and direct correlation method is analyzed. The simulation results of the measured ship noise show that the correlation performance of the split beam is good at low signal-to-noise ratio, but the performance of both is close with the increase of the signal-to-noise ratio.
