TV Wiretapping Surveillance System and Method for Detecting Wiretapping using Filtering Illegal Radio Frequency with Radio and Television Broadcast Frequencies

摘要

The present invention is installed in a vehicle to determine the location of the area where the vehicle is moving using a radio or TV broadcast signal, and to detect illegal radio waves generated inside the vehicle by filtering the surrounding radio waves according to the moving position of the vehicle. The present invention relates to a wiretapping detection system using an illegal radio wave filtering method based on radio and TV broadcast signals and a wiretapping detection method therefor. The present invention is installed in a vehicle to detect a radio wave inside the vehicle, use a radio or TV broadcast signal to determine the location of a moving area of the vehicle, and detect an eavesdropping signal capable of filtering radio waves according to the moving position of the vehicle An eavesdropping signal is determined by analyzing the detected radio wave using an algorithm, a eavesdropping event is generated when the eavesdropping signal is determined, and frequency information on the detected radio wave and a signal of the detected radio wave according to the eavesdropping event and a radio wave detection device for storing spectral data composed of intensities.
