The polarization dependent nature of ultra wideband (UWB) scattering from a radar target is studied using time-frequency (TF) analysis. The UWB frequency responses of the target under linear and circular polarization incidence are studied. The results demonstrate that the Q-factor of the resonant peaks vary as the incident polarization changes, indicating that different layer SEM poles are extracted...
Numerical models of a hip prosthesis model sited within two different realistic human tissue models have demonstrated that the E-Pulse technique is capable of detecting target depth changes inside a frequency dependent lossy halfspace. The performance is highly related to the dielectric properties of the half space and the excitation frequency. The dispersive attenuation factor of the halfspace and...
