RF measurement methodology for characterization of low radar cross section test specimens

The methodology outlines the proper selection of RF measurement techniques and determination of their associated parameters. Types of scattering evaluated include that for spatially static test specimens, spatially dynamic test specimens, and combinations of the two. Utilization of the methodology allows for maximum characterization of first- and second-order scattering, interaction contributions, and scattering reduction techniques. The methodology is primarily designed to utilize the full capabilities of an outdoor ground plane radar cross section (RCS) range. The selection criteria, techniques. parameter calculations, and result types outlined can be determined in an orderly step-by-step fashion and integrated into a structured test plan. Utilization of the methodology eliminates the procedural guesswork inherent in present-day RCS characterization efforts and allows for accurate data collection. In addition, maximum scattering characterization of complex low RCS test specimens is possible.<>
