A method for detecting a continuous wave signal of a detector, the method comprising:
- moving a local signal frequency in which the detector sequentially oscillates local signals of each different frequency;
- processing external signals in which processing signals are sequentially generated based on the sequentially oscillated local signals and the external signals sequentially received during the movement of the local signal frequency;
- checking the local signal frequency in which a frequency of the local signal that causes the processing signals, among the processing signals sequentially generated, having a frequency of a detection band detected by the detector to be generated is checked;
- fixing the frequency of the local signal with the frequency checked in the checking of the local signal frequency;
- discriminating the external signals in which a detection signal is output based on the processing signals having the frequency of the detection band, and the detected external signals are discriminated as any one of a continuous wave signal and a frequency modulation signal based on the detection signal;
- and
- notifying target signal detection outputting a notification based on the discrimination that the detected external signals are continuous wave signals,
- wherein:
- the detection signal has an intensity value based on a frequency of the processing signals and
- the discrimination of the external signals comprises filtering the frequency modulation signal discriminating the external signals as the frequency modulation signal when the intensity value of the detection signal is changed equal to or lower than a preset threshold value.
