摘要
为了研究水下爆炸声脉冲引起的混响,基于射线理论,利用椭球的几何性质,建立了改进的三维近程双基地混响平均强度模型,推导出爆炸深度任意的双基混响平均强度预报公式。计算分析了爆炸深度和脉冲宽度对混响强度的影响,并与实验结果进行了比较,结果表明:爆炸深度对混响强度的影响相对较小,脉冲宽度越大,混响强度越大。
In order to research the reverberation generated by underwater explosion, an advanced three-dimensional short-range bistatic reverberation average strength model is established based on the ray theory, using the geometric character of ellipse, and formula for computing reverberation strength is deduced. The effects of explosion depth and pulse width on reverberation are analyzed. The calculation results are compared with the experiment data, which indicates that the effects of explosion depth on reverberation are relatively small, reverberation strength increases by the pulse width increases.
