| 摘要: |
| 主动毫米波导引头通过自主发射高频脉冲实现对目标的定位与跟踪，具有良好的抗目标雷达关机性能。圆锥扫描是一种有效的导引头寻的工作体制。借助傅立叶变换方法，从回波中提取出目标雷达相对导引头机械轴的角误差及其初始方位，利用这两个参数就能对导引头轨迹进行实时校正，从而实现对目标的精确瞄准。仿真结果验证了新方法对目标角误差和初始方位的估计性能。 |

| Abstract: |
| Active MMW seeker can locate and track the target by emitting high-frequency pulse, and possess satisfying adaptability to suddenly cut-off radar while conical scanning is one of the effective seeker-steering systems. This paper aims to distill from the echo of the target location-related angles via Flourier Transformation, for these angles can be used to revise the attitude and course of the seeker timely, so that the target is kept in sight commendably. Numerical simulations were carried out to verify the satisfying performance of the proposed method. |
