摘要
介绍了一种基于目标能量特性的被动声引信。通过分析目标经过声引信时的能量变化信息,得到一种寻求最佳起爆时刻的方法。试验结果表明,利用接收声源级的差值判断目标是否最近距离通过,从而决定是否输出起爆信号,这种方法可以寻求到最佳起爆时刻,为被动声引信的应用提供了重要的依据。
In this paper,a passive acoustic fuse method is presented based on energy feature of target.Through analyzing the information of energy change as a target passes by the fuse,a method of seeking the optimum time for detonation is obtained.By considering the sound level differences of receiving signal to decide whether the target is passing by at a minimum distance,and then by making the decision whether the detonating signal should be output,the optimal detonating time can be sought.Experiment results show its rationality.
