摘　　要：雷达/红外双模制导过程中,提出了目标距离由雷达提供,目标视线角位置或角速度由雷达和红外融合提供.通过对目标被测误差角变化规律分析,提出了分布式结构中基于目标视线角速度的航迹融合方法,运用极大似然估计法进行了航迹状态估计融合.通过仿真,验证了该方法的有效性,提高了目标跟踪性能.In processing of the guidance by radar and infrared sensor, it is put forward that the target distance is provided by radar,and the angular position or the angular speed of the line-of-sight of target is provided by data fusion of radar and infrared sensor. By analyzing variable regulation of the measured angular error of target, the track fusion method based on the angular speed of the line-of-sight of target in distributed structure is provided. Track status fusion is achieved by the way of great likelihood estimation. This method is verified effectively by simulation,improving the capability of target track.
