多目标航迹相关算法及仿真研究

讨论不同位置上两传感器跟踪空中多目标的航迹相关问题，这里传感器a有距离、方位测量；传感器b有方位、仰角测量。算法分粗相关检验与精相关检验两步，后者采用从似然比检验导出的航迹相关性能指标，它特别适用于目标作编队飞行或交叉飞行。仿真结果显示，算法的效率接近理论的相关概率。

A Track Association Algorithm and Simulations

The problem of track association for multiple target tracking via two sensors is studied in the paper. The sensor-A measures range and bearing, while the sensor-B measures the bearing and elevation. The algorithm consists of two steps: first step is rough correlation test and the second one is a fine correlation test. In the second step the performance index is obtained from the likelihood rate test, and is applicable to formation flight and cross flight of multiple target. The simulations show that the efficiency of the algorithm is close to the theoretical correlation probability.
