RCS and antenna test bodies provide several helpful functions in EM test ranges. The RCS test body can serve as a pylon termination or an in-situ mounting structure for platform antennas, gaps, cracks, inlets, exhausts, pitot tubes… DSC offers a variety of test body structures to accommodate most every RCS and antenna need. Test bodies are designed to rest on foam columns, attach to top-hat style AZ?EL rotators, and hang from string positioning systems (Inverted Stewart Platforms). Computational scattering models are available based on electrical size and configuration.
