| 摘 要： | 基于信号包络线相似性， 本文提出了特定场地地下爆炸的识别方法， 并将其用于一个特定场地地震事件分析， 以评估该方法对特定场地爆炸事件的识别效果. 结果表明， 在误警率约为6.3%的情况下， 事件间距小于15 km的爆炸事件漏检率约为0.5%， 事件间距在15—30 km范围内的爆炸事件漏检率约为5.0%. 与波形互相关方法相比， 本文方法大幅扩大了有效识别特定场地爆炸事件的空间范围.

| Abstract: | This paper presented a discriminant algorithm based on the similarity of wave envelopes to discriminate seismic events in the same site.The events in a fixed site were analyzed to evaluate the discriminating performance for underground explosions.The result shows good performance.When the false alarm rate is about 6.3%， the misclassification rate for explosions with inter-distance smaller than 15 km is only 0.5%， and that for explosions with inter-distance of 15—30 km is about 5.0%. Comparison with the result from the algorithm based on waveform cross-correlation indicates that the method in this paper can discriminate explosions with much larger inter-distance. |
