This work underlines the importance of properly modeling the directivity of the antennas and proposes an improved calibration strategy in the framework of microwave diffraction tomography. Experiments to prove the effectiveness of the approach are carried out with a system comprising two ultrawideband linear antenna arrays. In the configurations presented herein, targets are in the near-field of the...
We numerically demonstrate that an iterative inverse method based on a rigourous wave scattering model can be used to retrieve the profile of a rough interface from the complex scattering amplitude in far-field. The method of moments, that is a numerical resolution of the boundary integral equations, is chosen as direct model, so that large profiles, with tens of wavelength, can be reconstructed....
This work presents a new RADAR prototype built for the purpose of imaging targets located in a cluttered environment. The system is capable of performing Phase Conjugation experiments in the ultrawideband [2–4] GHz. In addition, applying the D.O.R.T. method to the inter-element matrix allows us to selectively focus onto targets, hence reducing the clutter contribution. We aim to experimentally explore...
