| Abstract: | Aiming at the difficulty of track initiation caused by the "flicker" of low signal-to-noise ratio target signal of high frequency surface wave radar, a track initiation method based on PS-VF-TBD is proposed in this paper. This method makes comprehensive use of the broadening characteristics and motion characteristics of the target signal in the echo spectrum, and uses the characteristics of PS-VF-TBD method to effectively accumulate the energy of the moving target, so as to improve the correlation probability between multi frame signals of suspected targets, and then improve the search probability of the real target and the success rate of track initiation. Through the comparative analysis of track initiation results and long-time tracking results of ground wave radar measured data and synchronous AIS information, the results showed that the proposed method could give better track initiation results than the track initiation method based on DP-TBD, improved the track initiation probability of "flickering" target of low signal-to-noise ratio at the far, and improved the target tracking performance. It has the ability to distinguish adjacent targets in range Doppler spectrum. |
