The invention discloses a water radio interference signal automatic positioning system and a positioning method. The positioning method comprises the following steps: monitoring an interference signalwhich is larger than a trigger threshold in a key frequency band by a radio monitoring station, transmitting monitoring data to a control center, and reporting that interference occurs in a key frequency band of the control center; automatically starting TDOA positioning by the control center according to the monitoring data; completing the preliminary positioning of the position of an interference signal radiation source according to a time difference error by the control center; and changing the position and the number of the radio monitoring stations participating in coordinated positioning according to a preliminary positioning result, so as to realize the positioning of the final position of the interference signal radiation source. According to the water radio interference signal automatic positioning method provided by the invention, by setting key frequency band information in advance, the short-time performance and the suddenness of interference signals can be monitored, thusthe automatic monitoring capability is improved; and by means of clustering analysis on positioning data information, ships where an illegal radio station is located can be accurately positioned.
Description
technical field [0001] The invention relates to a signal automatic positioning system and a positioning method, in particular to an automatic positioning system and a positioning method of radio interference signals on water. Background technique [0002] Radio spectrum resources belong to the state, which is the basis for the development of the information industry and an important strategic resource for a country. The frequency resources are scarce and the demand for radio applications is huge, and the contradiction between frequency demand and supply is becoming increasingly prominent. For the first time, related content on spectrum resource management was included in the Outline of the Thirteenth Five-Year Plan for National Economic and Social Development: "Optimize the allocation of national spectrum resources, strengthen radio spectrum management, maintain a safe and orderly radio wave order, rationally plan and utilize satellite frequencies and orbits resource."
