Abstract:In the electromagnetic space,the physical domain and information domain cannot be effectively integrated and the application of electromagnetic information lacks intelligence. A concept of intelligent electromagnetic space is put forward. The intelligent electromagnetic space should bear the ability of representation, understanding, predicting and decision making. Taking the model as the core, taking the software as the carrier, with highly data-driven, it can achieve accurate mapping of the physical world and provide intelligent decision-making services for the combat command and troop operations. According to the organization mechanism of electromagnetic space information, the problem of multi-source heterogeneous physics—information data fusion is further solved, and the technical framework is constructed. Some key technologies and implementation ideas are proposed,including Geographic Coordinate Subdividing Grid with One Dimension Integral Coding on 2n-Tree-N Dimensions(GEOSOT-ND) high-dimensional tensor modeling and computation, multi-domain electromagnetic space sensing and efficient storage, full-dimensional electromagnetic situation reconstruction and intelligent deduction, and grid data-driven application methods.
