Abstract:

In complex areas,there is a large amount of complex interference,especially the very strong scattering noise.To suppress these disturbances,it is needed to spread the array,but this method result in increasing elevation to damage effective wave band.Through forward modeling,waveform and spectrum analysis methods,it is concluded that in the exploration of a complex area,elevation difference restriction of geophone array must be less than 1/4 main wavelength is too conservative to suppress interference by large array technology,Elevation difference restriction of geophone array is variable parameter as protected different seismic wavelength,signal to noise ratio and other factors.Relaxation of elevation difference restriction,despite suppressing to effective wave,will be slightly stronger,but if the interference wave is suppressed in a greater degree,then to measure the signal to noise ratio is worthy.

Key words: complex area, geophone array, elevation difference
