Surface Field Measurements on Scale Models in the Time Domain.

Abstract

Time-domain measurements have been performed of the surface densities of current and charge induced on scale models when illuminated by a transient electromagnetic pulse in order to provide test points to validate numerical models. Three bodies--a cylinder, a crossed-cylinder, and a 1:100 scale-model 747 aircraft--were used in the experiments. Responses were measured for objects in a simulated free-space environment and in the proximity of a perfectly conducting plane. The measured time-domain data are fourier transformed to the frequency domain, and analyzed via parameter estimation algorithms to extract the complex natural frequencies of the structures.
