摘要
介绍了一种空间目标姿态角估计方法,并在此基础上生成了RCS反射图。该方法主要是在直角坐标系中对目标的运动特征用二次项进行描述,并用最小二乘估计求解二次方程,从而根据运动方程估计出目标的姿态角。实测数据验证结果表明,该方法能够有效地估计出空间目标的姿态角变化情况,并可反映出目标RCS随其姿态变化的规律。
A pose estimation method, curve approaching method,is introduced and RCS reflecting figure is created. Motional characteristics of target are described in orthogonal reference frame,and least square estimation is used to solve the quadratic equation. Experiments with real data show the method can estimate the pose of the space target effectively and it also can reflect the variety law of RCS along with the pose.
