“…Radar-guided air-to-air missile adopts composite guidance technology and uses advanced data link information network to realize overthe-horizon launch, which has good anti-electromagnetic interference ability and poses a great threat to the safety of our fighters and pilots. Therefore, it is of great significance to study the countermeasure technology of the radar-guided air-toair missile [1] .…”

With the rapid development of the radar-guided air-to-air missile, its precision strike capability has seriously threatened the survival of fighter aircraft. To address this problem, the jamming model of towed decoy to the radar-guided air-to-air missile is established. The influencing factors of the interference effect of towed bait are studied in this paper. Firstly, the characteristics of the radar-guided air-to-air missile are analyzed, and the missile motion model is established according to the kinematic principle of the missile. Then, combined with the towed decoy jamming technology model and the missile model, the influence of factors such as dry letter ratio and confrontation situation on jamming effectiveness is compared and analyzed. Finally, the usage rules of towed bait in air combat are obtained. The effectiveness of towed decoys against radar-guided air-to-air missiles is verified by simulation experiments, which can provide a reference scheme for pilots to get rid of enemy locks quickly.

“…Besides the development of various hydroacoustic equipments, it is of supreme importance to propose efficient hydroacoustic counter-measures to address the changing scenarios of anti-torpedo confrontation [4][5][6][7][8]. Given individual antagonizing scenarios, a few researches were reported on the anti-torpedo counter-measures of submarines [9,10].…”

Due to the great threat of torpedo against surface warships, an efficient hydroacoustic countermeasure system must output realtime strategies that can accommodate varied antagonizing scenarios. Aiming at the decision-making problem in the anti-torpedo hydroacoustic countermeasure cases, this paper proposes an intelligent adversarial strategy based on the game theory. By discretizing the strategy space of both sides, a matrix game model is established with the payoff characterized by the capture probability of attacking torpedo. An improved simplex algorithm is then developed to get the mixed-strategy Nash equilibrium of the game model, with which preferred avoiding strategies can be obtained to minimize the risk of being captured by the attacking torpedo. Based on the probabilistic view of preferred adversarial strategy, the launching strategy of floating acoustic decoy can be achieved, and the evasion trajectory of warship can be confirmed simultaneously. Numerical simulation demonstrates that the proposed method can generate realtime intelligent antagonizing strategy, and consequently, can improve the survival rate of surface warships in the of anti-torpedo countermeasure scenarios.
