基于模糊Hough变换的被动传感器系统航迹起始方法

提出一种基于模糊Hough变换(FHT)的被动传感器系统中的航迹起始方法。首先利用逻辑关系或规则初步排除鬼点,以降低计算复杂度,推导出被动传感器系统中的Hough变换形式。考虑到传感器系统误差和测量误差对检测结果的影响,将传感器系统获得的观测值模糊映射到参数空间,利用梯度信息降低计算消耗,求出参数空间的模糊累积矩阵,通过模糊推理确定出最终的航迹检测结果。实验结果表明,所提的模糊Hough变换方法能有效解决杂波环境下的航迹起始问题,且计算消耗小。

Track initialization algorithm based on fuzzy Hough transform for passive sensor systems

A method of track initiation based on fuzzy Hough transform(FHT) for passive sensor systems is presented.Firstly,some logical rules are introduced for ghost points elimination,which reduce the computation complexity,and the Hough transform for passive sensor systems is derived.Then,the measurements from sensors are fuzzily mapped into parameter space,and the fuzzy accumulator shows the possibility of existence of tracks.The gradient orientation is used for lower computational complexity.Finally,the detection result is obtained by fuzzy reasoning.Experiment results show that the proposed method could initiate tracks efficiently in noised environment with less computation requirement.
