摘　　要：提出了适用于被动传感器网数据关联的模糊数学模型,定义了模糊综合贴近度,基于模糊综合贴近度提出了模糊航迹起始算法.研究了最速下降法中搜索起始点选取、候选目标初始状态估计、目标检测、多义性处理等问题.模糊航迹起始算法的优点是不必已知杂波特性及目标探测概率.仿真实验结果表明,该算法能有效实现航迹起始.This paper presents a fuzzy mathematic model for data association applying to the passive sensor network and defines the fuzzy synthetic closeness. Based on the fuzzy synthetic closeness, a fuzzy track initiation algorithm is proposed. The selection of the starting points for searching in the steepest descent algorithm, the initial state estimation of the candidate targets, and the methods for target detection and multivalency processing are also discussed. The advantage of the proposed algorithm over the algo- rithms available is that it isn＇t necessary to know the distributed characteristic of the clutter and the detection probability of target. Simulation results show the proposed algorithm can initiate the tracks effectively.
