We welcome contributions for future installments of the Measurements Comer. Please send them to Brian Fischer and Ivan LaHaie, and they will be considered for publication as quickly as possible. Contributions can range from short notes to full-length papers on all topics related to RF measurement technology and its applications, including antennas, propagation, materials, scattering, and radar cross section. New or unique measurement techniques are of particular interest.While there are many radar cross section measurement (RCS) facilities around the world, very few are capable of making bistatic RCS measurements. Many of those that can are typically limited in the range of bistatic angles they can collect. This issue's Measure ments Comer paper describes a new indoor RCS facility capable of collecting bistatic data over a full hemisphere above the target. Of particular interest is the facility's ability to support investigations into near-field-to-far-field RCS transformations.
Abstract
A new indoor facility for electromagnetic measurements has been developed and built at the Detectability and ElectronicWarfare Laboratory, INTA, Spain. The system was designed to ex tend the previous capabilities so that not only monostatic but also bistatic radar cross section (RCS) tests could be easily conducted. Due to limited space, far-field radar cross sections in the system are restricted to small targets, but this layout will allow the researchers to investigate RCS near-field-to-far-field transformations. The system was also conceived to be versatile enough to carry out other tests, such as near-field antenna measurements, material-absorption measurements, and electromagnetic characterization of materials. The paper describes the novel concept behind the facility, and presents some preliminary measurement results on different applications.
