Evaluation of Digital Accelerometer Performance

H019 EVALUATION OF DIGITAL ACCELEROMETER PERFORMANCE D. MOUGENOT 1 and G. VOLKOV 2 1 Sercel B.P.439 44474 Carquefou Cedex France 2 Tyumenneftegeophysika Tyumen Russia Summary 3C Digital Sensor Units (DSU3) based on MEMS accelerometers were compared with conventional coiled phones during a 2D point-source/point-receiver test performed in Siberia. P-wave shot point comparison in the velocity domain evidences two advantages of the new digital sensor technology: no pick-up noise thanks to the full digital transmission from the MEMS sensors to the central unit; stronger energy in the high frequencies. Two possible methods for ground roll attenuation were tested on the DSU3
