基于序列相关检测法的地震波传播速度测量方法

Seismic wave propagation velocity estimation method based on serial correlation detection

在分析比较各种测量方法的基础上,设计并制作了一套地震波探测实验系统。该系统采用人工震源重复激发地震波序列信号,并采用高灵敏度的阵列传感器接收信号。对接收数据的处理结果的分析表明:相比于单脉冲相关检测法,序列脉冲相关检测法能减少随机误差,更准确地估计地震波传播速度。

On the basis of analyzing and comparing various measurement methods, an experimental system of seismic wave is designed and produced. The artificial s.eismic wave excitation source of re- peated sequences is used and the sensor array with high sensitivity is applied to receive the seismic wave signal. After processing the received data, the results show that compared with the single pulse correlation detection method, the sequence correlation detection method can reduce the random error and the estimation of seismic wave propagation velocity is more accurate.
