APPARATUS AND METHOD FOR DETECTING SIGNAL

A device and a method, for detecting signals, which effectively analyze and trace abnormal signals which are unintended or different from normal signals are provided. The provided device for detecting signals includes: a signal reception unit to receive signals from the outside; an analog/digital signal processing unit to determine whether a signal is an abnormal signal or not for the signals received in the signal reception unit based on a plurality of signal profiles which have different signal characteristics and obtaining the abnormal signals when the received signals are abnormal; and a user interface unit for displaying the abnormal signals through the analog/digital signal processing unit. The method of the present invention is more accurate than matching through an existing simple frequency/bandwidth search by detecting abnormal signals based on profiles which are designated by a user and is capable of distinguishing a type of transmitter.
