| 摘要: |
| 文中推广了文[4]的结果，并利用飞行器航迹的连续性，提出一种能较好地工作在飞行器偏离参考图坐标轴情况下的快速地形相关算法-推广的指标排序截获算法。它不仅可串行地处理实时图数据，而且在匹配过程中还能不断地给出粗略的配准信息。在一张实际地形图上的仿真表明，在偏角θ＜5°，信噪比 σx/σn=3时，CEP 在 50 米以下。 |

| Abstract: |
| In the paper a fast terrain correlation algorithm to be called the generlized ordering aequisition of statistics (GOAS) is proposed by means of continuity of the aircratt track，which is better adaptable when the course of aircraft drifts off the axis of reference image. The algorithm can not only serially process the data of real-time image but also continually gives rough match information.
Monte-Carlo simulations have shown that its performance was better for the drift angle θ＜5°and its CEP was less than 50m for SNR=3. |
