Jamming resource allocation aimed to data link based on simulant annealing algorithm

The rapid development of electronic technologies raise higher requirements on electronic jamming system and combat tactic continuously. In order to improve the survivability of battlefield, the power of interference source is limited to specified values. Under these circumstances, the collaborative interference of multiple tactical jamming sources towards multiple targets plays an ever increasing role in the approaching electronic warfare scenarios. The allocation of the various jamming resources becomes an urgent problem that needs to be resolved by the commander in charge. Considering that the impact of large power consumption of jammers leads to a quite low battlefield survivability, the research on jamming resource allocation attracts more attention in recent years. In order to obtain the optimal jamming effect by utilizing limited power of jamming resources, this paper proposes a jamming resource allocation method based on the simulated annealing algorithm. The proposed model takes into account the shortcomings of both the single interference mode and the fixed interference mode. The total interference power is used as the constraint condition in this algorithm, and the objective function for allocating jamming resources is built accordingly. The benefits of assigning power allocated to jammers are assumed to be finite, which applies to most real-world combat scenarios. Moreover, we consider the effect on bit error rate of different power allocation schemes, the target of which is to develop a model for jamming power allocation. And a scenario is defined by the information provided by the specific communication link. Computational results show that the proposed model can allocate jamming resource effectively and optimize the combat capability of electronic warfare systems. The research on simulant annealing algorithm provides some theoretical gist and new thoughts on jamming resource allocation and improves the decision-making ability of electronic warfare systems.
