摘　　要：针对区域防空系统多传感器管理中传感器分配的特点,分析了基于协方差控制的传感器分配策略;在交互式多模型滤波基础上,介绍了序贯IMMKF算法;结合矩阵摄动的相关理论,提出了基于最小Fisher信息阵摄动的多传感器管理算法,并给出了相应的计算步骤,为传感器分配提供了一种新途径;文章结合仿真结果说明了该方法的有效性与可行性。The strategy of covariance control is analysed with regard to the characterist of sensor allocation in multi-- sensor management. Sequence IMMKF is introduced based on interacting multiple model algorithm. Then a multi--sensor management algorithm based on minimal Fisher information matrix perturbation is proposed and the calculation steps is given, which is a new method to sensor allocation. Finally, an application example is given and results show that the method is effectivity and feasibility.
