融合航迹与真值航迹的正确相关性判断是进行多传感器数据融合性能评估的基础,传感器的探测精度对融合系统的性能具有较大影响。文中提出了一种新的融合航迹判断技术,通过计算参与融合的各传感器探测精度,并作为融合航迹与真值航迹之间相关性的距离判断阈值,提高了判断的处理效率和准确度。通过工程应用,证明了算法的可行性。

The correct mutuality judgment of fusion track and true track is the basis of the capability evaluation for the multi-sensor data fusion. The detecting precision of sensor has great influence on the capability of fusion system. This paper presents a new technique of fusion track judgment which calculates detecting precision of every sensor participating in data fusion and makes the precision as the judgment distance threshold of fusion track and true track, thus improving the processing efficiency and accuracy of judgment. Engineering applications prove the feasibility of the algorithm.
