In view of the problem that a single UAV cannot timely capture the movement status in-formation of the target,it is easy to lose track of the target.Combining the unscented information filtering(UIF)algorithm with the interactive multiple model(IMM)algorithm,a multi-UAV dis-tributed fusion estimation algorithm based on IMM-UIF is proposed.The observation information from each UAV is transferred to a central node and the control inputs of each UAV is uniformly optimized.The simulation results show that the tracking accuracy of the multi-UAV distributed fusion estimation algorithm based on IMM-UIF is about 30％higher than that of the single UAV based on IMM-UIF,and the measurement information of the multi-UAV platform is effectively integrated to achieve stable and high-precision target tracking.
