More Information
Summary:The invention provides an illegal broadcasting station detection method and a system thereof, which are used for solving the problems of large workload and low positioning speed of searching illegal broadcasting signals in the prior art. According to the detection method, broadcast signals of FM frequency bands in a detection area are searched through an intelligent frequency point search algorithm, the center frequency point of the broadcast signals is determined, 16-64 paths of broadcast signals are automatically and continuously monitored through a multichannel analysis module under the 40MHz bandwidth with the center frequency point as the center, DDC analysis is carried out, illegal broadcast signals in the searched broadcast signals are identified, and finally direction-finding positioning is carried out on transmitting equipment of the identified illegal broadcast signals according to direction-finding equipment and a positioning algorithm. According to the invention, deep monitoring is carried out on
