T13 — Transformations for Radar Cross-Section (RCS) and imaging from monostatic near-field measurements

Summary form only given, as follows. True far-field (FF) radar cross-section (RCS) measurements of full-scale targets are often impractical to perform because of the large distances and/or large compact range reflector required to produce a plane wave illumination of the target. This fact has led to a requirement for techniques that can infer FF RCS from limited (specifically, monostatic-only) measurements in the near-field (NF) of the target. In this tutorial, we will present an in-depth derivation of a family of mature, self-consistent, and accurate near field RCS transformations that are based on models that are used in synthetic aperture, tomographic, and other forms of radar imaging. These image-based techniques have been successfully applied in practice to a wide range of targets and measurement configurations.
