Abstract: In this paper the mathematical statistics is used to investigate the effect of Doppler Effect on holographic acoustical imaging and then an expression through phase increment that depends on Dpppler Effect is introduced. According to the formula obtained it is possible to explain satisfactorily the series of experimental phemomena and results that had been observed and obtained by P. N. Keating et al. in the testing of moving object imaging. At the same time, the formula can be used to predict the proper data that will be necessary as objects are imaged by the system. And hence, satisfying holograms or holographic data and their reconstructing images can be obtained.
