地方震短周期速度记录与加速度记录时域仿真对比

Comparative Study on Time Domain Simulation between Short Period Velocity Records and Acceleration Records in Local Earthquakes Monitoring

摘要: 采用时域递归仿真算法，对成都市台网同台址地方震短周期速度记录与加速度记录进行相互仿真处理，并做了对比分析。结果表明，地方震短周期速度记录和加速度记录相互仿真结果与原始观测记录的时域、频域特征吻合程度较高，误差一般不超过10%；当监测目标为中小地方震时，短周期地震计与强震计可相互替代。

Abstract: The short period velocity record and acceleration record of the same station in Chengdu network is mutual simulated by the use of the time domain recursive simulation algorithm. And the results show that, the time domain and frequency domain characteristics of the simulation results are consistent with that of the original observation records, and the error is generally not more than 10 percents. The short period seismometers and strong seismometers can be replaced in a way during the small and medium local earthquakes monitoring.
