提出了基于辐射声信号估计水下爆炸当量和爆炸深度数量级的一种方法。该方法确定了爆炸形成气泡的第一次、第二次脉动周期的比值,气泡脉动周期从记录在水听器上的信号倒谱中提取。该方法应用结果显示:爆炸炸深度和爆炸当量的报告值与使用该方法的估计值的数量级相一致。该方法存在低估爆炸当量的偏差,这种偏差是由海上爆炸和实验室测量值规模不同造成的。
A method to estimate the underwater explosion equivalent and the depth of explosion based on the radiated acoustic signal is proposed. The method determines the ratio of the first and second pulsation cycles of the bubbles forming the explosion, and the bubble pulsation period is extracted from the signal cepstrum recorded on the hydrophone. The results of this method show that the reported values for the depth of explosion and the explosive equivalence are consistent with the orders of magnitude estimated using this method. This method has the bias to underestimate the explosive equivalent, which is caused by the different sizes of the sea explosions and the laboratory measurements.
