摘　　要：由于雷达对目标角度测量精度低,而红外传感器角度测量精度高,所以引入红外角度数据用以修正融合航迹点的方位角。建立了自适应α-β滤波的数据关联快速算法模型。进行了模拟战场实际目标的仿真试验。仿真结果表明该算法充分利用了红外与雷达的互补性,达到了降低目标航迹的方位角和俯仰角跟踪误差的目的,使航迹状态估计更加精确。Because of the lower precision of targets azimuth gained by radar, azimuth gained by infrared sensor with higher precision is introduced to revise azimuth precision of targets fused. In addition, FAFDA model based on Adaptive α-β Filter is established. Lastly, simulation experiment for targets simulated in battlefield is conducted. The experimental result validates that the algorithm can real-time track targets and makes good use of merits be- tween radar and infrared sensor to have reduced rapidly azimuth error of targets fused.
