The electromagnetic spectrum, as the core carrier for the transmission of communication signals and the bearer of information, is an important technical field in future electronic warfare applications. The core of it lies in the game between the ability to identify communication signal characteristics and the ability to hide them. This report introduces the development history of electronic warfare, summarizes the technical systems and capability directions from both offensive and defensive perspectives, analyzes the impact of the rapid development of AI technology on the two types of technologies of communication signal characteristic identification and communication signal characteristic hiding in the future, and explores from the theories of typical signal modulation recognition and low-intercept transmission of signal characteristics empowered by AI. Guided by the communication scenario of unmanned aerial vehicles, it proposes new waveform modulation and multi-dimensional feature hiding methods, aiming to provide new ideas and methods for the development of future electronic spectrum control game theory and technology application.
