摘要：
This letter reports on the characterization of two-dimensional targets from measured transient scattered fields. The problem is formulated in the frequency domain rather than directly in the time domain, and an iterative construction of the unknown dielectric constant is derived. Improvement of the resolution is suggested by marching on in the central frequency of the incident pulse. The efficiency of this approach is emphasized through examples of reconstructions of an inhomogeneous target from experimental data. (c) 2006 American Institute of Physics.
