The number of decoys deployed is very important for the operational effect in practical war actions, and the more number of decoys deployed, the better is the jamming effect. However, in the development of decoys, the cost-benefit factor is most important. So it is important to study the problem of decoy's cost-effectiveness. In this paper, a mathematical model has been established to study the problem of the cost-effectiveness of decoys.
