摘要
为提高空中多运动平台的协同探测能力,构建了一种多运动平台多传感器系统,提出了一种相应的目标跟踪方法。该方法将不同运动平台上的传感器对目标的观测转换到地心直角坐标系中进行融合跟踪,针对平台的运动和传感器的视域有限的特点,设计了序贯融合滤波算法。理论分析和仿真结果表明该方法既可以提高目标的跟踪精度,也可以扩大平台的感知范围,从而提升平台的探测能力。
A multisensor system based on multiple moving platforms is constructed and a target tracking method is proposed to en- hance their cooperative operations in this paper. Combination of multisensors is implemented in the earth-centered coordinates by transforming the measurement. A sequential algorithm of multisensor fusion is designed to meet the need caused by the motion of platforms and restricted area of sensors. Theoretical analysis and simulation results show that the algorithm can improve target tracking performance and enlarge surveillance volume.
