一种基于PDA滤波的多传感器管理算法

由于传感器资源或计算资源的限制,监视系统在跟踪多目标时通常不能同时为每个目标分配所有的传感器.因此,希望在满足目标跟踪性能的前提下尽可能使用较少的传感器.针对PDAF目标跟踪算法的特点,选用目标状态估计协方差的期望作为性能度量,提出了一种基于协方差控制的传感器算法.该算法通过为每个目标选择恰当的传感器组合来实现多传感器对多目标的分配.

Multisensor Management Algorithm based on PDAF

Surveillance systems tracking multiple targets often do not have the sensing or computational resources to apply all sensors to all targets in the allocated time intervals.Hence,Sensor management schemes have been proposed to reduce the number of sensors in the premise of satisfying the target tracking performance.In this paper,according to the character of PDAF target tracking algorithm,selecting the expectation of target state estimate covariance as a measurement index,presents a covariance control algorithm.This algorithm applies all sensors to all targets via one target selecting the appropriate sensor combination.
