DESIGN OF TARGET SUPPORT COLUMNS USING EPS FOAM: PREDICTIONS VS. MEASUREMENTS

摘要

When making large scale RCS measurements on a ground bounce range, EPS foam columns are frequently used as target support structures for test bodies and air vehicles. Thus, the design of foam columns is a key part in preparing for a large-scale outdoor test. Range engineers require foam column design methods and tools that are both efficient and reliable. This paper describes effective foam column design methods and shows comparisons of predicted column RCS to column measurements performed at NRTF. These comparisons give credibility to the concept of foam column modeling and ground bounce range scattering simulations, and give range engineers confidence in their foam column design process.
