“…The ship start to make a circular motion around the vector hydrophone at 0°.We take the time from 20s to 50s and estimate the position of the ship by using MUSIC algorithm,it is shown in Figure 8. Date the Figure 8(a) used is the raw data that the target ship collected.Figure8(b) use the date which is filtered by narrow-band.Line spectral analysis method [8] is used by filtering and we pick up the feature line spectrum of the ship then to filter.By comparing Figure 8 (a) (b),it can be known that the vector array can track the ship's track effectively and the tracking will be clearer and the accuracy of the DOA estimation will be higher after filtering.…”

“…These structural patterns are important for periodic signal detection. The power spectrum of ship radiated noise consists of wide band continuous spectrum and discrete narrow band line spectrum [1]. The former represents random noise' power distribution, while line spectrum contains important signature information related to ship's inherent vibration characteristics.…”
