摘　　要：针对目标数目未知和被动传感器测量精度不同情况下的航迹起始问题,提出一种基于多站被动传感器系统的航迹起始算法。该算法首先利用多规则法对测量数据进行预处理,消除一部分"鬼点",然后将模糊集的思想引入Hough变换,利用模糊函数的隶属度作为参数空间累积量,最后通过序列Hough变换检测航迹。仿真实验表明:该算法可有效改善航迹簇拥现象,抑制虚假航迹的产生,适合于杂波环境下目标的航迹起始。To solve the problem of track initiation typically encountered in the presence of unknown number of targets and different precision of detection,a track initiation algorithm for a multi-stations passive sensor system is proposed. First,measurement datas are preprocessed to eliminate a part of false observation points using multi-rules method,and then Bring fuzzy set into Hough transform parameter space. Use membership degree of fuzzy function as space accumulation of parameters. Finally,tracks are detected by the serial Hough transform. Simulation experiment show that this algorithm can effectively improve the track crowding phenomenon and constrain the appearance of false tracks,so this algorithm is available to initiate the track under dense clutter environment.
