Abstract:

A detailed investigation of the radar cross section RCS of extremely thin, spherical shells is described. The shells are taken to be thin enough to be neutrally buoyant in air when filled with a light gas such as helium. The problem is formulated and various approaches for calculating RCS values are explored for both dielectric and conductive shell materials. An exact solution is found to be necessary. The computer codes to carry out this solution are described, together with an extensive set of numerical results. In addition, a limiting solution is presented which furnishes the analytical basis for a correlation of the exact conductive shell results. This correlation provides a simple, working tool for predicting the RCS of very thin, conductive shells in the resonance region without recourse to the computer code. Author
