Electromagnetic situation representation based on parallel coordinates and radial coordinates

The representation of electromagnetic situation (EMS) is a key step in spectrum management and decision support in battlefield. In the past, 2-D and 3-D visualization methods were the only options for electromagnetic environment representation, but the complexity of electromagnetic environment of modern battlefield demands for a higher level of visualization of mass-information. Thus, we propose a new method to visualize EMS based on multi-dimension information visualization technology. To achieve this, we represent several key factors of electromagnetic field in a multi-dimensional coordinate system, and the corresponding domains are visually presented by the introduced parallel coordinates and radial coordinates. Simulation results show that this method can illustrate the EMS in a single coordinate effectively, which could provide excellent decision supporting and plan-aiding for users.
