| Abstract: |
| In this paper, the typical target tracking methods of high-frequency surface wave radar (HFSWR) are briefly summarized. Subsequently, a method of continuously tracking vessel targets using HFSWR is presented. The basis of this new method is to take full advantage of existing trajectory characteristics, establish a ship motion model based on characteristics and echo data, and make a fusion decision combined with clutter characteristics. Furthermore, in order to satisfy the need of continuous tracking over a long time, the idea of deep learning is applied and the estimation results are recursively corrected with new arc segment data. Therefore, the tracking is more accurate with more obtained data. This method realizes the real-time stable tracking of a maneuvering target trajectory in a cluttered environment even in a channel with a lot of ship interference. The method contributes to the theoretical basis and guidance of tracking specific targets with HFSWR continuously and stably and in complex environments with serious clutter/interference. Moreover, the method offers technical support to enable HFSWR play a significant role in maritime surveillance. |
