Intelligent air-based threats are considered as the main elements of terrorist attacks which damage vital infrastructures. Air defence systems with a strategic and decisive role in defense networks require smart management and operational mechanisms to countermeasure the threats and risks both quickly and decisively. The main objective of this investigation was to develop a spatial methodology to reduce the vulnerability of infrastructures against airborne threats. The proposed method tried to detect the threatening parameters of air-based threats and the vulnerability parameters of infrastructures in order to find a solution for deviating airborne threats equipped with GPS and INS. The proposed method was implemented for the power electric infrastructure in Isfahan, Iran. The authors tried to identify the most probable routes for airborne threats targeting such strategic infrastructures. More specifically, the aim was to mislead the threats and deny access to infrastructures and finally to locate the optimum sites for the deployment of jammers. Eventually, the proposed method showed to reduce the total number of jammer positioning processes to a desirable level. The results indicated that the number of jammers decreased by about 28% and the extent of damage was reduced by 57%
