可用联立微分方程组来计算单个空气枪或空气枪组的合成特征信号。方程组包括三个主要部分:(1)理想的自由振荡的空气泡的性态,(2)空气在枪膛中的性态和枪口打开时气泡的性态,(3)振荡的气泡及它们产生的压力波场之间的相互作用的一阶方程描述。这三个部分过去曾经被其他人讨论过;第一部分可用来计算每个空气枪的特征信号,第二部分用来计算特征信号的脉冲部分,对于多枪组合,我们证明了一般说来这三部分必须综合起来才能计算可实现的,完善的合成特征信号。
The simultaneous differential equations can be used to calculate the composite signature of a single air gun or air gun set. The system of equations consists of three main parts: (1) the behavior of an ideal free-flowing air bubble, (2) the behavior of the air in the chamber and the behavior of the bubble when the muzzle is open, (3) the oscillating bubbles and The first-order equation describing the interaction between the pressure wave fields they produce is described. The three parts were discussed by others in the past; the first part was used to calculate the signature of each air gun, the second part was used to calculate the impulsive part of the signature signal, and for multi-gun combinations we proved that the three Parts must be synthesized in order to calculate the achievable and perfect synthetic signature signal.
