TLDR
In this paper, the performance of single offset compact antenna test ranges with different reflector edge treatments and rim shapes was compared using the physical optics technique, and a comparison between reflector edges taper and rim serrations in controlling edge diffraction was demonstrated.Abstract:

A compact antenna test range based on a hologram
TL;DR: In this article, a planar hologram structure is used as a collimating element for the reflector-type compact antenna test range (CATR) at 119 GHz.

Edge coatings that reduce monostatic RCS
TL;DR: In this paper, the electromagnetic consequences of placing a dielectric coating at the edge of a conducting plane are discussed and an empirically based coating design strategy is formulated that uses asymptotic RCS data and surface wave attenuation data to determine those properties of the coating that will effect a reduction in monostatic RCS at obtuse incidence angles and H-polarisation (magnetic field polarised parallel to the edge).

Near-field radiation characteristics of shaped electrically large apertures in the spatial and angular domains
TL;DR: In this paper, the aperture near-field angular spectrum can be expressed as the product of the angular domain spectrum of the aperture field and the angular-domain spectrum of spatial network response function.

Dual-reflector compact range modelling: geometrical theory of diffraction analysis and sub-millimetre quiet-zone computation
TL;DR: In this article, the uniform geometrical theory of diffraction (GTD) is used for dual-reflector compact range analysis at millimetre and sub-millimetre wavelength.

Compact Range Performance Evaluation Using Aperture Near-Field Angular Spectrums
TL;DR: In this paper, the characteristics of the aperture design have been carried by the aperture near-field angular spectrum, which can be separated and distinguished clearly in the angular domain by making an inverse Fourier transform of its aperture spatial near field.
