A Generalized Interpretation and Prediction in Microwave Imaging Involving Frequency and Angular Diversity

Angular spectral‐domain inversion of a conducting cylinder by using the physical optics approximation

“…' (53) (54) and n: = prey. This result corresponds with the solution found in [4]. In the space domain the TJ3 and TM sources are now laminar sources along the z axis for the decomposition of a dipole in the origin.…”

“…Imaging of a perfectly conducting object may be obtained by using the Bojarski and Lewis formulation [l, 21 under the physical optics (PO) approximation, which shows a Fourier transform relation between the object shape and its backscattered far fields. This formulation is extended to twoand three-dimensional bistatic configurations [3, 41 for which the Fourier transform reconstruction is equivalent to the backprojection algorithm of the x-ray tomography and interpreted as a frequency and angular diversity [4].…”

Microwave image understanding and its applications to various imaging schemes

“…From this approach, the representation, interpretation, and prediction of images for given spectral and angular windows can be made. Generalized interpretation and prediction in microwave imaging involving frequency and angular diversities has been described [13]. When the Fourier space data are accessed in a polar format or in an Ewald sphere, it can be shown that the Fourier transform reconstruction of the range-Doppler method is equivalent to the tomographic backprojection method.…”
