Abstract: | This paper analyzes Wigenr-Ville distribute and its application in extracting of signal's instantaneous frequency. Then it combines PC radar signal's characteristics, puts forward a method for detecting PC radar signal. This method bases on intermediate frequency digital receiver, and adopts Wigenr-Ville distribute. Lastly, computer simulations are carried aiming at simulate radar signals and practical radar signals. |
