In recent years， artificial intelligence technology has been widely used in national defense and other fields， and has achieved relevant breakthroughs. In view of the lack of systematic summary and analysis on the comprehensive application of artificial intelligence technology in shipborne weapon system， based on the full investigation of foreign literature， the application of artificial intelligence technology in the field of detection and identification， command and control and firepower strike in shipborne weapon system is summarized， and insights are presented. The application of artificial intelligence technology in shipborne weapon system is summarized， and the future development trend is proposed in order to provide some reference for the application and development of domestic related technology.

Aiming at the technical problems of simple anti-interception method and insufficient anti-interception ability in traditional spread spectrum， frequency hopping and time hopping techniques，， an anti-intercept technology based on weighted-type fractional Fourier transform（WFrFT） and modulation hopping is proposed. The properties of the original signal have been changed with the constellation rotation， expansion and diffusion by WFrFT. Meanwhile， combined with modulation hopping technology， different carrier frequencies correspond to different signal modulation modes. The proposed method improves the confidentiality and security of information transmission in the complex and changeable electromagnetic environment.
