Abstract:The traditional electronic reconnaissance system lacks flexibility and its ability to perceive complex electromagnetic environment is limited. It does not have the ability to obtain indepth information such as behavioral intention and environmental situation analysis, and has poor adaptability to unknown signals and dynamic environment. For the above problems, this paper studies the key technologies of electronic reconnaissance system, such as intelligent decision making, adaptive adjustment and electromagnetic situation estimation. It realizes the closed loop process of autonomous environment perception, evaluation judgment, autonomous planning and autonomous execution, and improves the intelligent level of the system and the perception ability of battlefield electromagnetic environment.
