鱼雷双维尺度声靶回波信号的方位走向识别方法

摘要

论文在鱼雷双维尺度声靶模型基础上，基于 Matlab 语言和鱼雷接收声基阵，对接收的双维尺度声靶回波信号进行仿真分析，用方位走向方法在回波信号里提取出靶标的方位走向信息，得出回波信号水平方位走向和垂直方位走向的态势图，推导出方位走向方法能够有效的对尺度目标的尺度信息进行分析和识别，双维尺度靶标能够更加逼真的模拟潜艇目标的双维尺度特性，为鱼雷尺度识别的的后续研究提供可靠有力的参考和依据。%In this paper ,analysis and simulation of the echo signals is conducted based on the torpedo model ,Matlab and sound receiving arrays .The bearing trend information of the target for torpedo is extracted with the identification meth‐od ,illustration to the horizontal and vertical direction of the echo signal is obtained .Finally the conclusion is made that the i‐dentification method for the bearing trend can recognize the dimension information of the scale target ,the two‐dimensional scale sound target can be more realistic simulation of submarine target .This paper provides a powerful and reliable reference for future research to dimension recognition of target .
