Abstract:
Abstract-Here we present the application of Time reversal-
MUSIC algorithm for the microwave imaging of early breast
cancer detection by using UWB signal illumination. The breast is
modeled as a two dimensional homogeneous lossy dielectric
medium. The time reversal MUSIC algorithm is used to find the
image of malignant tissue in a cluttered environment created by
back scattering from the breast tissue heterogeneity. A preprocessing
method is utilized on received signal to extend the use
of the proposed algorithm for UWB frequency range. The time
reversal MUSIC technique is applied at the output of the receive
antenna array to determine the location of malignant tissue by
making use of dielectric contrast at microwave frequencies.
