A strong emphasis is now being placed on techniques for reduction of radar cross-section, A missile or aircraft which is invisible to radar has an important strategic advantage. With this fact in mind, the user of a weapons system may place an upper limit on the radar cross-section that he will permit his missile or aircraft to have. The designer must then make use of "stealth technology" to reduce the cross-section to an acceptable level, In order to verify the design, radar cross-section measurements must be made. Thus the current emphasis on cross-section reduction leads to an important need for accurate and reliable methods of measuring radar cross-section.
In this article a method of radar cross-section measurement is described. It utilizes a compact range configuration, More widely used as a tool for measuring the radiation patterns of microwave antennas, the compact range can also be applied to the problem of radar cross-section measurement. A heuristic development which illustrates the principles of compact range operation is presented and the coupling equations for both the antenna measurement and the radar cross section measurement cases are derived.View The Paper
