Identification of Scattering Mechanisms from Measured Impulse Response Signatures of Several Conducting Objects.
Abstract
The backscattered impulse response of several perfectly conducting objects has been measured and qualitatively compared to several theoretical predictions. The value of the impulse response waveform as a time history of scattering behavior is due to its unique relationship to geometry of the scatterer. This relationship is explored for local diffraction mechanisms, multiple diffraction between separate points on the scatterer, creeping waves, and natural resonances. Finally, it is demonstrated that a time domain view of a high frequency solution such as the Uniform Geometrical Theory of Diffraction offers a physically intuitive explanation for individual scattering mechanisms and multiple interactions.
