AI Technical Summary

Technical Problem

Existing radar anti-jamming methods lack optimization for key moments during the game process, resulting in insufficient concealment and effectiveness, making them easy for the jamming party to identify and counter. Furthermore, conventional methods fail to comprehensively consider the impact of the duration distribution characteristics of different working stages on the game outcome.

Method used

A radar anti-jamming method based on key moments in a game is adopted. By combining a parameter setting module, a remaining game time prediction module, an anti-jamming behavior selection module, a jamming behavior selection module, a timing module, and a win/loss determination module, the radar's behavior selection at key moments is optimized, the remaining game time is dynamically predicted, and the winning probability is statistically calculated, thereby enhancing its stealth and effectiveness.

Benefits of technology

It improves the radar's success rate in anti-jamming at critical moments, enhances the radar's stealth and effectiveness, and significantly increases the probability of winning in the final round of the game. It is suitable for anti-jamming scenarios when radar attacks surface ships with cruise missile platforms.

Abstract

The application provides a radar anti-interference method based on a game key time point, and the method comprises the following steps: setting game parameters before the game starts; predicting the residual game time before the current round starts according to the residual game time before the last round of game starts and the time used in the last round of game; the radar performs win rate statistics on each candidate behavior, selects the behavior corresponding to the highest winning probability, selects an interference behavior according to a Markov decision process, and counts the time used in each round of game; and determining whether the radar is in an advantage when the game ends and outputting a game result. The parameter setting module of the system is connected with the residual game time prediction module, the residual game time prediction module is connected with the anti-interference behavior selection and timing module, the anti-interference behavior selection module is connected with the interference behavior selection module, the interference behavior selection module is connected with the timing module, and the timing module is connected with the win-loss determination and residual game time prediction module. The method and system can enhance the concealment and peculiar effect of radar anti-interference.
