分布式异类传感器网异步采样下的航迹起始算法

为解决分布式异类传感器网异步采样下的航迹起始问题,基于模糊集理论,定义了测量集与目标间的模糊综合贴近度。基于模糊综合贴近度提出了分布式异类传感器网航迹起始算法。该算法通过模糊综合贴近度函数全局极值点的检测实现目标的检测,用与目标相关联的测量估计目标的初始状态。算法的特点是不需要掌握目标探测概率、虚警率、杂波密度等诸多信息。仿真实验验证了算法的有效性。

Track initiation algorithm for distributed heterogeneous sensor network under asynchronous sampling condition

To solve the problem of track initiation for distributed heterogeneous sensor network under asynchronous sampling condition,the fuzzy synthetic approximation between the set of measurements and a target is defined based on the theory of fuzzy sets.On the basis of the fuzzy synthetic approximation,an algorithm is presented for track initiation in a distributed heterogeneous sensor network,which detects the targets by detecting the global extreme points of the fuzzy synthetic approximating function,and estimates the target's initial state by the correlative measurements with the target.The algorithm does not need any additional information such as the probability of detection,false alarm rate and clutter density.Simulation results show its effectiveness.
