摘　　要：为了充分利用雷达和红外探测器的测量数据的各自优势,提出了一种雷达/红外数据融合方法。以最小二乘理论为基础,利用雷达测量值及其测量时间前后红外探测器高频测量的冗余信息,并通过引入时间维度和测量维度两个权重因子,获取了对目标的最优估计。仿真试验结果表明,与等权融合方法相比,本文获取的融合数据信息能够更好地反映出目标的运动状态,并能为后续目标跟踪提供更为准确的观察值。To make full use of the advantages of the data measured both by a radar and by an infrared sensor,a fusion method for radar and infrared data is proposed.On the basis of least square theory,the radar data and the redundant information of an infrared sensor when it measures at a high frequency before and after the radar measures are used.The optimal estimation of a target is obtained by incorporating two weighting factors：time dimension and measurement dimension.The simulation test result shows that compared with the equality weighting factor fusion method,the fusion data information obtained by the proposed method can reflect the motion state of a target better and can provide more accurate observation value for the subsequent target tracking.
