| 摘 要： | 提出了一种弹目之间相对距离的估算方法。该方法基于相邻图像帧之间目标特征点的匹配,提取具有旋转不变性的特征线度信息,结合目标在弹体坐标系中的高低角和方位角,从弹目初始距离出发,通过定位方程实现递推测距。仿真结果表明,它具有测距精度高、被动定位的特点。

| Abstract: | This paper gives a new algorithm of the relative distance between missile and target.That characteristic dot matching is requested in adjacent frame,then the characteristic linearity information with rotational invariance is extracted.With the pitching and azimuth of the target in missile coordinates,from the original distance between missile and target,the range is recurrently deduced through location equation.The simulation results show that this method has some speciality such as high measurement precision and passive location. |

| Keywords: | angle infrared image characteristic linearity missile-target distance range finding algorithm |
