“…The finite separations between the transmit/receive antennas and the target limit the size of targets that can be measured complying with the far field criteria. A compact range illuminates a target with a plane wave and allows for far-field measurements to be conducted in a small area [1], [2]. Literature concerning bistatic RCS measurements of targets in a compact range is limited and restricted to measurements at fixed bistatic angles.…”

“…In 1993 one study investigated the ability to perform bistatic RCS measurements in a compact range by measuring the bistatic scattering of an electrically large PEC flat plate [1]. This measurement setup consisted of a transmit antenna and a receive antenna which were positioned on either side of the focal point, defocusing the parabolic reflector.…”

This paper illustrates the ability to perform bistatic radar cross section (RCS) measurements at a fixed bistatic angle in a compact range. Literature regarding bistatic RCS measurements in compact ranges is limited. The traditional setup of a compact range was adapted to perform bistatic RCS measurements. These bistatic measurements were conducted on canonical and complex realistic scale airframe models. The targets were illuminated with a plane wave created by an offset parabolic dish reflector. The bistatic scattering of the targets were measured by placing a receive antenna at a fixed bistatic angle and finite distance in the compact range. This paper also investigates the effect of the finite separation between the targets and the receiver on the bistatic scattering measurements of large complex targets. The accuracy of the bistatic RCS measurements are compared to full-wave simulations conducted with FEKO using the Multi-Level Fast Multipole Method (MLFMM) solver. Quantitative comparisons are drawn between the simulations and measurements using the Feature Selective Validation (FSV) method.
