Localized Short-Pulse Scattering from Coated Cylindrical Objects: Experimental Measurements and Numerical Models
This paper presents some results of our investigations into transient scattering from finite cylindrical targets. One unique feature of this work is that the vector field measurements were performed with non-planar excitation in the near-field of the target (localized measurements). Two electromagnetic models were developed to predict the transient near-field scattering and were validated by extensive comparison to measurements. One was a finite-difference time-domain (FDTD) model, while the other was based on the method of moments technique. The complexity of the field behavior in the near-field region provided a challenge for the model validation efforts. In this paper we discuss the measurement techniques, the electromagnetic models, and present the results of representative scattering measurements to highlight some of the interesting behavior which was observed.
