%X In order to improve the resolution of TEM to detect buried targets, a new multi-aperture transient electromagnetic survey configuration is introduced and used to survey TEM response in this paper. Both of multi-aperture system and normal TEM configuration in the condition of different receiver-transmitter distances are used to observe the primary field and secondary field corresponding to copper-plate. The response curves and the surveyed data error of two kinds of configuration are compared. It has been found that the multi-aperture transmitter system can improve the primary filed intensity higher more than 34%, and bring the secondary field response high more than 31%. The survey result shows that the multi-aperture TEM transmitter configuration can really change the distribution of magnetic field. It is suggested that there really exists the phenomenon of TEM field coherent-like .It is of significance to improve the precision of TEM data.
