A New Analysis Method for Multi-component Linear Frequency Modulated Emitter Signals
To effectively detect and recognize multi-component Linear Frequency-Modulated(LFM) emitter signals, a multi-component LFM emitter signal analysis method based on the Independent Component Analysis(ICA) which was combined with the Wigner-Hough transform was proposed. The idea which was adopted to this method was the time-domain separation and then time-frequency analysis, and in the low SNR cases, the problem which is generally plagued by noised of feature extraction of multi-component LFM signal based on Wigner-Hough transform is overcame. Compared to the traditional method of time-frequency analysis, the computer simulation results show that the proposed method for the multi-component LFM signal separation and feature extraction was better.
