For horizontal single-layer and multi-layers model, the SNR of seismic waves is presented when the single source and single source directed synthesis techniques are used, and the simulation results show that the single-source directed synthetic seismic waves could effectively improve the SNR of seismic waves. Through the analysis on the SNR improvement due to the directional lighting synthesis of field data, the SNR of directional synthetic records based on single-source is improved by the average of 6.4041 dB comparing with the SNR of single source. The effects of seismic exploration are effectively improved., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null,
