Observation of Diffraction from Absorber Array and Field-Probe Using Long Vertical Objects

Abstract

A compact range lined with rows of absorbers on all sides would offer a unique opportunity for the curious mind to study its diffraction effect even under very dim illumination [1]. An extended long object usually gives rise to a bright reflection (glint) when viewed near its surface normal. To take advantage of this phenomenon, a discrete Fourier transform (DFT) on RCS measurements would yield a spectrum of incident wave distribution along that object [2, 3]. Some interesting physics are discussed.
