摘　　要：雷达与红外数据融合能够实现信息互补,改善对目标的跟踪、识别以及提高系统的生存能力。为了解决空中目标高速机动时,单一模型的雷达/红外序贯滤波跟踪发散的问题,提出了一种基于序贯滤波和交互多模型的雷达/红外融合跟踪机动目标的方法,通过在雷达与红外序贯滤波融合中引入交互多模型来跟踪机动目标。仿真结果表明,该方法与基于最优数据压缩的雷达与红外传感器融合跟踪机动目标相比,跟踪精度明显提高,是一种雷达与红外传感器融合跟踪机动目标的有效方法。Radar and Infrared data fusion can reinforce information for each other,improve target tracking ability and enhance system viability.The radar/infrared sequence filter based on single model will diverge when tracking highly flexible aerial target.In order to solve this problem,a radar and infrared fusion method to track maneuvering target based on IMM and sequence filtering was proposed in this paper.The fusion method tracks maneuvering target by introducing IMM to radar/infrared sequence filtering.Simulation results show that,comparing with the radar and infrared maneuvering target tracking method based on the optimum data compressing,the method can significantly improve the target tracking performance.The fusion method is effective for radar/infrared to track maneuvering target.
