阵列信号处理在地震震源位置及震级估计中的应用
|
摘要
提出了对重点地区和地震频繁爆发地区进行地震震源位置估计的新思路,并运用阵列信号处理的理论对该思路进行了详尽的数学分析,建立了实际地壳的复杂非均匀传输介质模型,并将该模型转换为一种简单的均匀传输介质模型;之后给出了具体的算法和计算机仿真模拟结果。容易发现,运用该思路对特定地区进行地震速报,将可以摆脱地震监测中震源定位难的困扰。
The first section of this paper presents a new approach to estimate the location and magnitude of seismic origin in the important area and the region suffered frequently from seism.The approach is mathematically analyzed in detail.The notable achieve-ments include the model of realistic lithosphere fabricated with complicated nonuniform transmission media and its shifted simplified al-ternative constructed with uniform transmission media.And then a concrete algorithm is detailed for clarity followed with the simulation results generated by computer.It is easy to find by the new approach people are probably free of the puzzle in locating the hypocenter for the special monitored area.
