针对具有不同误差雷达和AIS传感器对于船舶航迹跟踪模糊关联问题,提出船舶航迹分数阶关联算法.利用分数阶的记忆性质,将分数阶微分对时间序列局部趋势的度量引入关联算法中.实验证明,分数阶较整数阶关联算法可为船舶航迹关联决策提供更丰富的支持,提高了船舶航迹关联的精度.

Aiming at the radar and AIS sensor＇s fuzzy association to ship tracking caused by different errors,the fractional order ship tracking correlation algorithm was provided.By taking advantage of the memory property of fractional order,the algorithm introduced the measurement of fractional order differential for the local trend of time sequence into the correlation algorithm.Examples show that the fractional-order association algorithm can provide much more related information and improve the ship tracking correlative accuracy.
