According to the theory of systematic engineering, by combining tactic and technology, this paper proposes some top design on how to protect the land-based radar information grid through electro-optic protection. It discusses the principle and methods of constructing synthetical electro-optic protection, highlighting its key technologies. Considering the practical construction of anti-destruction for land-based radar information grid, it puts forward the integrated design thoughts about information grid electro-optic synthetical protection. It is very important to improve synthetical survivability and operational effectiveness of land-based radar information grid.
