| Abstract: | Digital channelized receiver is the broadband reconnaissance receiver used most widely in electronic warfare. This article combines the concept of short-time Fourier transform （STFT） with digital channelization, explains the channelization principle based on STFT, validates the correct- ness and feasibility of this method ＆ the capability to measure signal time-frequency parameters and distinguish multiple signals through Matlab simulation. |
