In the present work features of travel time processing is discussed. These data are received during surveys using deep-tow system by means of standard procedure called the CMP method. The main difficulty of this task is correction of source-receiver geometry. This means true location reconstruction of source-receiver configuration as well as the reflection point location. Methods allowing to eliminate the difficulty and to process the data using the CMP method are given in this paper. Special attention were focused on the source-receiver geometry method of correction. This method bases on both refraction waves and ghost-waves travel time measurements and allows receiving the main geometrical parameters without using an additional seismic technology. Possible applications, merits and demerits of this method are shown. In addition an influence of source-receiver geometry correction to further processing graph is given.
