Abstract: The paper introduces a set of processing and interpretation software for transient electromagnetic synthetic aperture imaging data, which can realize the interpretation of the target and the fine imaging by using transient electromagnetic wavelet transform preprocessing techniques, differential conductance imaging, depth correction technology and wave field pulse compression technique. Finally, the synthetic aperture calculation method realized high resolution imaging of transient electromagnetic data. According to the combination of several methods, the software of processing and interpretation system for transient electromagnetic synthetic aperture imaging was developed. The software realized the calculation and fabrication of the raw data from the transient electromagnetic data to the synthetic aperture imaging. The data processing method and the image processing interpretation software can improve the resolution of transient electromagnetic interpretation.
