Using Multiple Sources Of External Information To Conduct An Aerial Tracking Technology

As the science and technology continuous to development,from the era of traditional weapon to the era of information warfare,the war on information between the countries has been strengthened,which is pushing the development of mordern national technology in our country.Based on the background of the traditional air and early warning radar,the radar synergy of external sensors for space target correlation and fusion,made in the case of a large amount of data kept operation speed and improve the detection precision and scope,play a greater role in auxiliary set sail,which provides strong guarantee for China's national defense.(1)The paper introduced the research status of track-to-track association and fusion,pointed out that China in the field of track association and fusion there is still a gap with western,described the research background and significance.(2)The internal acquisition and external acquisition mode of track information are introduced,and the shore-based air sea early-warning radar,ads-b and AIS are introduced in detail.By analyzing the different conditions,the importance of track association and fusion is discussed in detail.(3)The study analyzed the nearest neighbor correlation algorithm.On the basis,according to the large amount of data of air-sea shore-based radar,this paper proposed using the genetic variation of the algorithm to solve the problem of track association.Using genetic algorithm and nearest neighbor algorithm for track association simulation by Matlab in the situation of the large amount of the near tracks,through calculating OSPA worth out of the conclusion of the two algorithm can prove that GA is better than NNDA in the situation mentioned before.(4)Introduced the engineering application environment.The hardware system adopts the Power PC hardware platform and the hardware operating system Vx Works6.8,and the software development environment is the Workbench.And in combination with the actual project,the course implementation process of the whole project is realized,and the flight path association module is introduced in the design of the whole project.It also shows a radar and an ads-b for the empty mode and the video for the real track and the tracks.
