Abstract An analysis of electromagnetic backscattering data using Wavelet Packet Transfrom (WPT) is presented. Due to its adaptive multiresolution property. WPT is well adapted to resolve the multiscale features of backscattering data. In particular, with respect to the consequence of analysis and computational complexity, WPT results in a better representation of backscattering data over Continuous Wavelet Tramsform (CWT) which was employed by II. Kim, H. Ling (1992, 1993). So WPT method makes a contribution to the time-frequency analysis of the electromagnetic
wave. Furthermore, it is shown that WPT method offers a new approach for the further application of wavelet to instantaneous magnetic field.
