Concerted Systems for Increasing the Survivability of the Aircraft against Terrorist Threats

The paper explores the threat posed by terrorism in aviation domain, especially surface-to-air missile attacks against transport aircraft. While the focus of this paper is the mitigation of security risks in the aviation domain, the proposed solution based on concerted countermeasure systems discussed here may be developed in the context of homeland security policy promoting the principle of flight safety. The reception and the processing of data through the detection of signals emitted by various sources are proceeding in the absence of users interest about the form of the wave of the message. The detection of the presence / absence of the signal or the identification of its value is proceed by identifying the signal associated to each value of the message, considered a discrete variable, hence triggering of the adequate defence mechanism.
