PURPOSE: A signal jamming method is provided to store a phase value of signals of a predetermined frequency band in which a jamming target signal is included based on the phase value. CONSTITUTION: A jamming target signal is searched for in a jamming range(S602). Phase information is extracted from the searched jamming target signal. Extracted phase information is stored within an hour(S605). Noise information is reflected based on search condition information. A jamming signal based on the phase information is outputted(S609).
