Text-fixture-based antenna scattering measurements

Text fixtures are commonly used to measure the radar cross-section (RCS) of flush-mounted antennas. These test fixtures are typically designed to provide a clutter-free region in which the antenna can be mounted. In addition, the test fixture provides an electromagnetic environment for the antenna which is similar to that found in the final application. Proper design of these test fixtures must take into account factors such as positioning subsystem capabilities, signal processing capabilities, and desired measurement sensitivity and accuracy. Once the test fixture design is established, proper test planning will yield the maximum amount of diagnostic information from each measurement
