Conceptual studies for unmanned hardened radar facilities

A baseline design concept is developed for a hardened, unmanned, phased-array radar facility. Among the subjects discussed are functional design requirements and constraints, concepts examined, design trade-offs, and special considerations and problems associated with the structural design. The selected configuration is described and a parametric study of the adaptability of the baseline design to varying levels of nuclear threat is discussed. Preliminary cost estimates are presented. While this study is performed for a specific facility, the method of approach is readily adaptable to other hardened facilities. Of special interest is the reliability analysis which was developed for multimode of operation systems, using Markov processes theory; this is described in some detail.
