  • Numerical Study of the RCS of Pyramidal Absorber Geometries

    Abstract—There have been a number of numerical analyses of RF absorber. These however, tend to focus on the reflectivity of the material not on the radar cross section (RCS) that it presents. Brumley studied the RCS of RF absorbers as a way to estimate the background RCS of anechoic ranges [1]. The study was done empirically, doing measurements of the RF absorber, and looking at the RCS of different pyramids, with and without paint. Brumley presents some potential ways of improving the RCS signature of the range thus reducing the background RCS of the site. In this paper the suggestions presented by Brumley are revisited.

  • Numerical Analysis of Techniques to Improve Oblique Incidence of Absorber

    Abstract—Financial impacts often drive decisions to repurpose existing ranges instead of procuring new measurement facilities. These existing ranges have fixed geometries (height, width and length) that were set when the range was originally constructed and often are designed for a different purpose. The inability to set the geometry precludes the range designer from using the range geometry to improve measurement performance. Read More
  • Using High-Accuracy Swing Arm Gantry In Spherical Near-Field Automotive Measurement Systems

    Abstract—Spherical Near-Field (SNF) systems using a swing arm gantry configuration have been the “go to” solution for automotive measurement systems. Recent advances in the automotive industry have warranted a need for SNF systems with high mechanical positioning accuracy supporting measurements up to 40 GHz and beyond. This paper presents the design and implementation of a new swing arm gantry positioner having an 8-meter radius and a radial axis to support high frequency SNF measurements. Read More
