Full-domain collaborative deployment method of multiple interference sources and evaluation of its deployment effect

This paper realizes the full-domain collaborative deployment of multiple interference sources of the global satellite navigation system (GNSS) and evaluates the deployment effect to enhance the ability to disturb the attacker and the capability to defend the GNSS during navigation countermeasures. Key evaluation indicators for the jamming effect of GNSS suppressive and deceptive jamming sources are first created, their evaluation models are built, and their detection procedures are sorted out, as the basis for determining the deployment principles. The principles for collaboratively deploying multi-jamming sources are developed to obtain the deployment structures (including the required number, structures in demand, and corresponding positions) of three single interference sources required by collaboratively deploying. Accordingly, simulation and hardware-in-loop testing results are presented to determine a rational configuration of the collaborative deployment of multi-jamming sources in the set situation and further realize the full-domain deployment of an interference network from ground, air to space. Varied evaluation indices for the deployment effect are finally developed to evaluate the deployment effect of the proposed configuration and further verify its reliability and rationality.
