“…Therefore, it is appropriate to measure the local perforating destructive probability (ProbLP) of debris clouds by the size of the perforation area (Area FC ) they cause on the compart-ment of a spatial target and its related parameters in the full digital simulation. Furthermore, referring to a previous study [16], we create the following evaluation model of Prob LP .…”

“…Therefore, the specific impulse per unit area I SP (MA) generated by debris clouds can be taken as a measure of the tearing destructive probability (Prob TF ). In the full digital simulation, it is assumed that the large-area tearing destructive effect of debris clouds is like its strong shockwave effect; accordingly, we can create the following evaluation model of Prob TF by referring to the strong shockwave destructive criterion [16].…”

This paper proposes an all-sided performance evaluation system including the test system with its evaluation models and detection methods for satellite navigation countermeasures to meet the manufacturers’ needs for improving critical performance in production and design and satisfy the decision-makers’ demands for expanding the benefit of the global navigation satellite system (GNSS) in game. GNSS are adopted as the evaluation object, and a performance test system are established around the composition of the GNSS, the properties of satellite navigation countermeasures and their performance evaluation principles, solving the one-sidedness and imperfection in current evaluation systems. Subsequently, the evaluation models for performance indices and their detection methods are proposed around the active protective capabilities including disturbing the GNSS users and destroying its ground control segment and spatial satellite segment, as the basis for realizing the performance evaluation and quantitative analysis. Finally, the impact of each performance on the corresponding ability is analyzed through case-based simulations and tests, whose obtained results can propel the decision-makers into selecting the optimal strategy and further maximizing the protective benefit of the GNSS.

“…Nevertheless, in this subsection, comparison of the proposed to three existing schemes is provided. In particular: (a) the complexity of the proposed scheme is compared to the complexity of a linear scheme [69], where the concept of omni-directional propagation of the blast wave is presented, (b) the threat notification time of the proposed scheme is compared to the one presented in [70], where sensors/cameras are mounted along the perimeter fence of a CI and (c) the estimated surveillance equipment cost of the proposed scheme is compared to the cost of [71], where surveillance of the area of a CI is accomplished by a grid of sensors.…”

“…In the linear case (omni-directional wave propagation), the threat is estimated for all cpbs, irrespectively of their distance from the blast. Figure 12 illustrates complexity of the proposed scheme and of [69] for a random selection of 300 different time instances (300 instances of possible explosion). As it can be observed, the proposed method reduces computational complexity compared to the linear approach.…”

Real Time Threat Assessment of Truck Cargos Carrying Dangerous Goods for Preventing Terrorism Attacks on Neighboring Critical Infrastructures

Critical infrastructures are assets of invaluable importance, essential for the whole world. Since they serve core functions of our societies, they often become targets of terrorists. Many critical infrastructures are vulnerable, due to their short distance from public roads and in the past years, several vehicle-bomb incidents have been recorded. This paper focuses on the case of truck-bombs, which can either be created from scratch, or terrorists can easily hijack truck cargos carrying dangerous goods and turn them into bombs. The latter are typically called ADR truck cargos, according to the respective agreement of the 30th of September 1957, concerning the international carriage of dangerous goods by road. The proposed scheme performs threat assessment of neighboring critical infrastructures, aiming at preventing explosions of truck-bombs. To do so, each crucial point of a critical infrastructure is initially associated with a level of importance. Next, three scenarios are analyzed: (a) single-attack single-infrastructure, (b) multiple-attack single-infrastructure, and (c) multiple-attack multiple-infrastructure. To reduce computational complexity, the third scenario is simplified to one of the two other scenarios, by introducing a novel fusion technique for the non-overlapping segments of the Voronoi tessellation. By this way, an area of threat assessment is estimated for each critical infrastructure. Then, the threat level is assessed in real time by an innovative algorithm, which: (a) estimates the impact of multiple consecutive explosions, (b) uses five adapted threat levels and (c) introduces multiple criteria and minimum classification conditions based on the number of crucial points and their levels of importance. Extensive real world experimental results and comparisons to other works, exhibit the pros and cons of the proposed scheme. In particular the proposed scheme improves: (a) computational time by 74.5%, compared to [69], (b) threat notification time by 86.9% compared to [70] and (c) estimated surveillance cost by 98.6% compared to [71].
