The principles of passive defense in the immune defense structures funeral maintenance of strategic items

The purpose of this study was to investigate the principles of passive defense in landfill structures of strategic defense items. The research is done using descriptive-analytical method. This is an applied research. Methods and tools for collecting information In this research, questionnaires were used for library and internet searches. SPSS software was used to prove the validity and reliability of the questionnaire and was calculated using Cronbach's alpha method. The findings indicate that the principles and considerations of passive defense (location, coverage, retrofitting, hiding, camouflage, deception and dispersal) play a key role in the construction of landfills for strategic items. The most important indices of locating principle: Safe area selection in geography of the country, soil strength of the area, area air, the most important indices of covering principle: use of complex stairs such as polyhedral and concealment of the main identity of structures, the most important indices of retrofitting: application of plasma membranes, increased thickness and , Combining Multi-Immunization and Reinforcement Techniques, The Most Important Indicators of Principle of Conservation: Constructions in valleys, mountainous and buried areas near shores, The most important indices of camouflage: The use of thermal, multispectral and artificial camouflage fans, the most important indices L trick: use a fan pretense, false attack, deception, simulation and deformation technology, the most important indicators of the dispersion: miniaturization, pluralism and development facilities and structures are funeral.
