6. A method of radio supervision based on data multidimensional features, applied to the apparatus of any one of claims 1 to 5, the method comprising:
measuring through the receiving antenna, the electromagnetic measuring module and the signal analyzing module, obtaining electromagnetic environment data, and sending the electromagnetic environment data to a Fourier transform module;
acquiring non-electromagnetic parameter data through the environment parameter measurement module, and sending the non-electromagnetic parameter data to the data processing module;
processing the acquired electromagnetic environment data through the Fourier transform module; obtaining electromagnetic spectrum data and sending the electromagnetic spectrum data to the data processing module;
correlating the electromagnetic spectrum data and the non-electromagnetic parameter data based on the same geographic position through the data processing module, generating correlation data and sending the correlation data to the data center;
acquiring external data from an external data interface through the data center, fusing and visualizing the external data and the associated data, generating visualized data and sending the visualized data to a terminal;
importing national radio frequency division data into a frequency division table of a self database through the data center; and importing existing radio service data into a service database, wherein the radio service data comprises a correspondence of authorized radio services and frequencies;
carrying out service division, occupancy analysis and display on electromagnetic spectrum data through the data center; calibrating the known service according to the database of the service;
when the unknown service is identified through the data center, the transmitting time, position and frequency information of the radio corresponding to the unknown service are stored in an abnormal transmitting table in a database, and an abnormal notification is generated and sent to the terminal;
when the radio of the unknown service is identified through a signal analysis module, if the identification result is legal, the data of the radio of the unknown service is newly added to the service database, and meanwhile, the data of the radio of the unknown service in the abnormal sending table is deleted; and if the identification result is illegal, marking the service type and the modulation mode of the unknown service.
7. The method of claim 6, wherein the circumscribed data comprises GDP, demographic data, and social event information, radio security time, and geographic location.
