Direction of arrival (DOA) estimation is an important problem in array signal processing.An effective multiple classification (MUSIC) method based on the short-time Fourier transform (STFT) and forward/ backward spatial smoothing (FBSS) techniques for DOA time-frequency (t-f) joint LFM sources addressed.Previous work area e. g.STFT-MUSIC algorithm cannot resolve t-f completely or largely because they can only select single-source points.The proposed constructs distributions (STFDs) by...
Based on Dechirping algorithm and uniform circle array (UCA), a new 2-D direction of arrival (DOA) estimation linear frequency modulation (LFM) signals is proposed in this paper.The uses the thought regards signal to be estimated which received by reference sensor as proceeds difference treatment with each sensor.So becomes single-frequency sensor.Then we transform an isolated impulse through Fourier (FFT) construct data model based prominent parts impulse.Finally, respectively use multiple...
