The effect of different positions of the receiving/transmitting antennas on microwave inversion results is discussed. Ten different transmitting/receiving configurations are employed to seek the relation between the antennas positions and the accuracy of inversion results. The synthetic study shows that these ten configurations lead to almost the same result.
A method to enhance microwave tomography through the use of an inhomogeneous background is proposed. Here, the measurement region is located in a circular perfect electrical conductor (PEC) chamber where known objects are placed inside the imaging domain as an inhomogeneous background. The Green function of a circular PEC chamber with inhomogeneous background is obtained using the method of moments...
Different kinds of a priori information used to enhance microwave tomography are introduced and classified into two main categories. The first main category of a priori information is about features of target, these can introduce some information of the target to the tomography algorithm. This type of a priori information can lead to a better initial guess and an appropriate regularization as well...
