| 中文摘要: |
| 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. |
| 英文摘要: |
| 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. |
