Abstract

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
