Abstract
To solve the problem of emitter separation under complex electromagnetic environment, a signal separation method based on digital channelizing was proposed in this paper.A two-level structure which could divide signal into dif-ferent channel was designed first.After that,the peaks of different channels were tracked using the track filter and the co-incident signals in time domain were separated in time-frequency domain.Finally,the time domain waveforms of different signals were acquired by reverse transformation.The validness of the proposed method was proved by experiment.关键词
