摘　　要：为了提高目标跟踪系统的性能,在吸收雷达和红外跟踪传感器各自优点的基础上,提出一种雷达/红外传感器信息融合方法,该方法综合了雷达测量信息全面以及红外测角精度高的特性,对雷达与红外量测进行融合形成融合量测,基于融合量测设计了状态估计滤波器。在不同假设条件下,分别对融合系统与单传感器跟踪精度进行了仿真比较。结果表明:融合系统的跟踪精度高于单个传感器的目标跟踪精度,可有效提高目标跟踪精度。To improve the performance of the target tracking system,a kind of radar and infrared information fusion method was put forward based on the combination of the advantages of radar and infrared sensors.With the help of this suggested method,the comprehensive measurements of radar and high accuracy angle measurements of IR were integrated,and a nonlinear filter was designed based on this integrated measurements.Data simulations of fusion system and the single sensor were finally proposed.Simulation results showed that the fusion system can significantly improve the accuracy of target tracking system compared with the single tracking sensor.
