Research On The Problem Of Low-Frequency Response Of Geophone Array In Seismic Prospecting

It is usually use geophone array to receive seismic signal in seismic exploration. Geophone array can depress ground roll and random noise in order to improve S-N ratio, however it can also bring stronger low-frequency response so as to reduce resolution. So far more research about geophone array concentrate on ability of certain array which can depress all kinds of noises, less on improving low-frequency response of certain array.In this paper, we aim at frequency-response function of simple linear array, making use of its least-squares reverse filter to convolute synthesis seismic data, furthermore contrasting the wave and spectrum so that analyzing the effect of this reverse filter in theory.
