In this paper mathematical statistics is used to investigate the effect of the Doppler effect onacoustical holographic imaging,and then an expression through phase increment that depends onthe Doppler effect is introduced.According to the obtained formula it is possible to explain satis-factorily serial experimental phenomena and results that had been observed and obtained in thetesting of moving object imaging by P.N.Keating et al.At the same time,the formula can beused to predict the proper parameters that will be necessary as objects with different velocity areimaged by the system.And hence,satisfactory holograms or holographic data and their reconstructedimages can be obtained.
