一种改进的基于速度信息的航迹关联算法

Algorithm for Track Association Based on Velocity Information

简要介绍了分布式雷达组网的工作过程及原理，讨论了航迹关联中的加权法和双门限关联法。进而提出一种基于速度信息的关联算法，利用机动目标交叉飞行时速度信息的差异，并且航迹采用粗、精关联相结合的方法。在特定的仿真场景中，对三种算法进行了比较，仿真结果验证了该算法的有效性。

The work process and principles of distributed radar net is discussed firstly. Two representative algorithms are discussed. Then an improved association algorithm based on velocity information is introduced, using the difference between across flight of maneuver targets, and the association algorithm includes two parts： coarse and precision correlation. Then the new algorithm is compared with these two algorithms. The validity of the simulation system is indicated by experimental results.
