| Abstract: | The detection and real - time processing of uhra-wideband （UWB） signals are one of the crucial problems in EW system. The profit and engineering implementation of STFT for LFM signals are analyzed, on the basis of which a method for real-timely detecting and recognizing UWB LFM signals with low SNR is presented with engineering applications. |
