Low-Cost Radar Cross Section Measurement With a Resin-Made Model Coated With Conductive Paste

This study aims to provide practical information regarding the development of a cost-effective test model for low-cost radar cross-section (RCS) measurements. Two major possible approaches reducing manufacturing cost are replacing molding material with an inexpensive one and measuring scaled-down higher operating frequency. In this study, former was achieved using resin-made coated conductive paste imitate complete metallic model. According scaling laws, entire geometry, including surface roughness because paint, must be appropriately scaled down. Because is practically infeasible, we experimentally prove that, if appropriate selected, shape-only valid without scaling. As preliminary two types polyurethane resins different densities were tested their suitability RCS measurements, resin density shown Based on 1/20- 1/40-scale aircraft models manufactured aluminum or resin, values measured demonstrate that almost equivalent patterns could obtained. Therefore, testing
