Design and data fusion method of vertical cable and small-track-distance towing cable combined acquisition system

The invention discloses a design and data fusion method of a vertical cable and small-track-pitch towrope combined acquisition system, and belongs to the field of seismic prospecting, the acquisition system comprises a working ship, an electrode, a vertical cable and a small-track-pitch towrope, the vertical cable and the small-track-pitch towrope are immersed under the sea surface, and when the system is specifically designed, the vertical cable and the small-track-pitch towrope are arranged in the working ship. According to the illumination range, the water depth, the seabed inclination angle and the incidence angle of the vertical cable, the arrangement range and the arrangement position of the optimal small-track-distance towing cable are determined; and when data fusion is carried out, vertical cable acquisition data are calibrated according to a small-track-distance towing cable acquisition data speed profile and an imaging profile. According to the scheme, the small-track-distance towing cable and the
