摘　　要：运用小波包分析方法对等药量、同距离处的FAE武器与TNT爆炸地震信号进行了分解重构,对各自在不同频段的能量分布进行了对比分析。结果表明,FAE武器爆炸地震信号的能量主要集中在低频,而TNT爆炸地震信号的能量相对分散,越往高频部分两者的能量幅值渐次降低。Using wavelet pack techniques to decompose and recreate the explosion seismic signals generated by the FAE warhead and the TNT charge with the same weights and distances, and analyze the energy distribution of the different frequency band respectively. The results show that the energy of explosion seismic signal of FAE warheads is concentrative in low frequency bands, while the energy of explosion seismic signal of TNT charge is decentralized than that of the FAE warheads. The energies of explosion seismic signal FAE warhead as well as TNT charge attenuates with the increase of the frequency.
