A single-view imaging strategy for transient scattered fields

Abstract : This paper deals with an approach to provide non-invasive characterization of inhomogeneous targets from knowledge of a transient scattered field. This last one is measured by using only one source, which radiates a Gaussian incident pulse. The problem is addressed in the frequency domain rather than directly in the time domain and the reconstruction capabilities of the proposed strategy are verified against experimental data. The experimental setup provides stepped-frequency data measured on a large spectrum support, with a small frequency step. Therefore, it is possible to synthesize pulses with different shapes. This allowed us to test the performance of the proposed inversion strategy. The presented results show that the reconstruction procedure takes advantage of the large spectrum of the incident pulse.
