基于高分辨距离像的目标姿态角估计算法

目标的姿态角是目标运动状态的一个重要参数，在目标监控、目标跟踪、目标识别、导弹制导律设计等多个领域都有着很广泛的应用。不同于传统的利用图像传感器得到光学图像估计目标姿态角的方法，针对有翼导弹等弹体目标跟踪应用中的姿态角估计问题，利用高分辨雷达得到的距离像，给出了姿态角估计的流程，提出了基于距离像匹配及运动状态滤波辅助的估计算法，并针对一个导弹末端机动场景实现了姿态角的连续跟踪，验证了本文提出的姿态角估计算法的可行性。

Pose estimation algorithm based on high range resolution profile

Pose information is one of the important parameters of target motion states, and has been applied extensively to many fields, such as target monitoring, target tracking, target identification and designs for missile guidance law. Different from the traditional algorithms using optical images obtained from an image sensor, a pose estimation algorithm based on high range resolution profiles (HRRP) obtained from a high resolution radar is proposed in the winged missile tracking application. The algorithm is based on profile matching and motion state filtering. A missile maneuver scene is constructed and the simulation results verify the feasibility of the pose estimation algorithm proposed.
