Abstract: Intelligent structure design is of great significance for improving design efficiency and realizing technological innovation. Aiming at the characteristics of radar structure design, such as multi-variety, small batch, fast updating and multi-disciplinary coupling, the present situation of existing structural design and methods, digital prototype and information technology is studied, the main problems at this stage are summarized, and the construction of integrated design and manufacturing platform, full three-dimensional collaborative design, intelligent data management and intelligent toolset are put forward. The realization method of radar intelligent design technology is presented. It is of great significance for improving design efficiency and intellectualization, and playing its guiding role in scientific research and production. Developing direction of future structural design technology is also preseated.
