This paper describes on methods in test and evaluation of the guided rocket munitions of the domestic new generation multiple launcher rocket system. We modified and refer to the present model of air-to-air missile(AAM) and surface-to-air missile(SAM). Also we suggested a method of surface-to-surface missile(SSM) based on the characteristics of the guided rocket in test and evaluation(T&E). According to this study, the suggested activity of T&E should be observed methods compatible with each item on the established model. Therefore, we expect that the proposed research material will be a good guide to the study of a surface-to-surface missile(SSM) installed GPS/INS integration navigation guidance & control systems in the future.

Radar Cross Section(RCS) is a measure of how detectable an object is with a radar. A larger RCS indicates that an object is more easily detected. Informally, the RCS of an object is the cross-sectional area of a perfectly reflecting sphere that would produce the same amount of reflection strength as the object in question would. In order to estimate RCS of aircraft weapons the external surface is modeled as a collection of simple shape elements. And the overall RCS is estimated as a vector sum of configuring elements' cross-sections which are well known given by analytic formulae. A RCS estimation code is developed for a typical shape of Air-To-Surface bombs and missiles. Size of weapons and location of fins are implemented in the code in addition to the presence of canards. The ability to predict radar return from flying vehicles becomes a critical technology issue in the development of stealth configurations. This simplified method of RCS estimation is known to be fast and accurate enough in an optical region of high frequency incident radio wave.
