1. A method of detecting an illegal broadband radio signal, the method comprising:

  • receiving, by a reception unit, a surrounding radio signal at a place where an illegal radio signal is to be detected;

    generating, by a detection unit, reference frequency information by configuring a reference multi-spectrum table in such a way as to generate a basic resolution spectrum by extracting a signal of a preset frequency band as basic resolution from the received surrounding radio signal and to generate a multiple resolution spectrum by extracting the signal of the preset frequency band as resolution of a positive integer multiple of the basic resolution from the received surrounding radio signal;

    generating, by the detection unit, detection frequency information by configuring a detection multi-spectrum table in such a way as to generate a basic resolution spectrum by extracting the signal of the preset frequency band as basic resolution from a detection radio signal detected in the place where an illegal signal is to be detected and to generate a multiple resolution spectrum by extracting the signal of the preset frequency band as resolution of a positive integer multiple of the basic resolution from the detection radio signal; and

    identifying, by a determination unit, whether a signal intensity value greater than a signal intensity value of the reference multi-spectrum table is present in the detection multi-spectrum table.
