A Digital Channelization Method Based on STFT
Kai Wang · Shipboard Electronic Countermeasure · 2013
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 correctness and feasibility of this method the capability to measure signal time-frequency parameters and distinguish multiple signals through Matlab simulation.
