| In recent years, data fusion has been widely used in both military and nonmilitary. And how to use the information from multi-radar effectively is one of the hot issues at present.After introducing the theory of data fusion, the paper set up a multi-radar video fusion system. Then detailedly analyzed the each module's working principle and resolution algorithm of the video fusion system. Firstly, introducing the concept of connectivity in image processing, cluster the points belonged to the same target to get the information of the video center according to the characteristics of radar video data. Secondly, filter the sea clutter and fixed point using the information accumulated during periods. And last, by space aligning, time aligning and targets clustering in data fusion center platform, the fusion center of targets was calculated. And the multi-radar tracking turns into the single radar tracking.For each algorithm in this paper, a detailed description and realization process was given. And the effectiveness of the algorithm is verified in chapter VII. |
