摘要/Abstract

摘要： 精密控制震源是精密主动监测技术的关键设备, 它为整个系统发射精确的、高度可重复的震动信号, 是精密主动监测的基础。其理论波形对于观测数据处理、提取监视地下介质的信息是十分重要和关键的。精密控制震源发出的震动信号由于受到重力的影响, 并不是标准的正弦或余弦波形。本文研究了重力对震源发射波形的影响, 推导出在重力影响下精密控制震源理论波形的计算公式, 给出了该计算公式的数字递推求解方法和误差控制方法, 可以准确地计算出精密控制震源在重力影响下发射信号的理论波形。

Abstract: The Controlled Accurate Seismic Source(CASS) is the key device for accurate active seismic monitoring system. It radiates accurate and highly repeatable seismic signal for the system, and is the basis of the accurate active seismic monitoring. Its theoretical waveform is essential to observation data processing and getting information about the crustal median changes. The signal radiated by CASS is not standard sine forms because of the effect of gravity. A method of calculating the theoretical waveform of CASS under the effect of gravity is presented, the formulas for it are deduced, and the digital calculation procedure is also given in this paper.

Key words: CASS, Theoretical waveform, Digital solution, Error Estimation, Error control
