Propagation environments of radiowave information systems

Radio systems are in contact with the channels of information transmission in high-tech information times tightly more and more. The channel becomes an important part of radio systems, which is known as the radiowave propagation environment. Digital grid data can not only reflect the continuous visibilities of different part of the radiowave environmental parameters, but can achieve the propagation forecasts and generate the necessary visual maps for any regions. Based on the radiowave space grid environmental information data from advanced remote sensing instruments and radiowave environment station networks, as well as the management and application of space-time information which is expressed by radiowave environment grid data, the radiowave environment observation and security system is realized with comprehensive observation system, abundant data acquisition methods, integrated earth space, and real-time information capacity that can be used in radar, communication, monitoring and control, navigation and other electronic information systems, and integrated security systems, etc.
