PURPOSE: A method for a real time search of signals existing in a wide frequency band is provided to deduce specific information of a signal by searching and processing a variety of signals on a real time basis. CONSTITUTION: A signal receipt & search block receives signals of an allocated frequency band by distinguishing a wide frequency band into a fixed interval, and down-converts the received signal to an intermediate frequency signal having a proper intermediate frequency signal to the signal process, and then converts the converted intermediate frequency signal to a digital signal (S100A-S100N). A signal process controller divides the converted digital signal to a segment digital signal which is distinguished into a fixed lower band, and analyzes the divided segment digital signal according to the time change, and then deduces segment signal information about the searched specific signals (S200A-S200N). The signal process controller deduces, stores, and outputs signal information of the entire frequency band existing in the entire frequency band region by putting all the searched segment signal information together (S300). [Reference numerals] (S100A,S100B,S100N) Receive a signal and convert into a digital signal; (S200A,S200B,S200N) Divide the digital signal and search and process digital signals of each segment; (S300) Draw entire frequency band signal
