Abstract

Multi-target DOA estimation by single vector hydrophones is strongly influenced by environmental factors. To further improve the accuracy of azimuth estimation. Azimuth of target sound source can be computed by single vector hydrophone. Receive the radiated noise emitted by multiple ships using a single vector hydrophone. Apply the Hilbert transform to the received sound pressure signal, followed by Fast Fourier transform (FFT) to obtain the multi-target line spectrum. Utilize cross-spectrum goniometry to compute the azimuth of each ship at every frequency point. And then the azimuth of each target is obtained by frequency analysis. Finally, the multi-target time azimuth diagram is drawn by scatter plot.
