Abstract :
An analysis of electromagnetic backscatter data using the wavelet transform is presented. The multiresolution property of wavelets enables scattering events with different scales in the frequency domain to be simultaneously resolved. The backscattered signal from a dispersive plasma cylinder is studied using the wavelet analysis. The different scattering mechanisms are clearly identifiable in the time-frequency representation.
