【摘要】 在分布式多传感器数据融合系统中,由于每个传感器的采样周期不同以及具有不同的通信延迟,导致送入融合中心的局部航迹往往不是同步的。提出一种多传感器异步数据融合算法,该算法首先利用最小二乘实现时域融合,将航迹同步化,然后利用一种序贯的Kalman滤波方法进行融合。更多还原

【Abstract】 In the distributed multi-sensor data fusion system,the tracks that the fusion center gets are not always synchronous,for the sensors detect the track at different rates and different communication delays.In this paper,an algorithm is provided.First of all,every asynchronous track is synchronized by Least Square algorithm at time domain.And then the paper also analyses this sequential Kalman algorithm.更多还原
