The recent development of vibrator electronics allows generating a family of comprehensive sweep signals including phase controlled sweeps. In proposed method the minimum phase equivalent of the standard reference linear sweep is calculated and then emitted to the subsurface. Recoded vibrogramm is correlated with original unchanged reference sweep. Output is minimum phase correlogramm which is ready for standard processing with minimum phase deconvolution application thus agreeing with minimumphase earth response assumption. This paper demonstrates the result of minimum phase controlled field experiment and it comparison with standard acquisition result.
