The traditional dynamic and static correction is difficult to implement in shallow surface medium, so that the same phase shaft is difficult to flatten, and the underground structure is easy to miss or misjudge; the three-dimensional earthquake uses reflected waves as detection means, and reflected earthquake rays have insufficient coverage on underground media, so that the effective detection area is insufficient.
Single point seismic mapping scheme: the single-point seismic mapping scheme only uses a pair of excitation-receiving combinations, and generally sets the offset to be the optimal offset, so that the offset is large, the system is difficult to deploy behind a vehicle, and the system integration level is poor, the layout efficiency is low, and therefore, the system can only be used on a closed road.
