單矢量水聽器頻域極化加權(quán)MUSIC算法
[Abstract]:Aiming at the problem that the estimation performance of classical multi-signal classification (MUSIC) algorithm is limited by spatial random distribution noise, a single vector hydrophone MUSIC algorithm based on frequency-domain polarization weighting is proposed. The polarization parameters of the received signal in frequency domain are extracted by this method. According to the polarization characteristics of the target signal and the noise, the spectrum of the received signal is weighted adaptively. The polarization covariance matrix is constructed by replacing the original received signal with the weighted spectrum signal, and then the target azimuth is estimated by the classical MUSIC algorithm. Simulation results show that the target azimuth estimation error is less than 5 擄when the SNR is -15 dB and there is no prior knowledge. The results of sea trial data processing verify the effectiveness of this method.
