Abstract :
Gabor deconvolution has been applied in seismic imaging in order to compensate for non-stationary effects encountered during wave propagation (G. F. Margrave, et al., Geophysics, 76, 15–30, 2011). We previously applied this method to signals collected during microwave breast imaging (K. Y. Liu, et al., URSI GASS, 1–4, 2014) for the purpose of compensating for the frequency-dependent attenuation of wave propagation in lossy and dispersive tissues; and improving the signal resolution by removing the excitation pulse in the recorded signal. The aim of this study is to investigate a frequency-dependent Q model that is able to more accurately describe the wave attenuation than the existing constant Q approximation, in order to provide us with better estimation results.
