摘要: 分析典型航迹的特征规律,根据多段航迹组合生成航迹的思想,运用3种基本的目标状态方程模拟刚体目标大机动飞行的三维航迹。针对模型切换时的航迹平滑问题,提出基于最小二乘拟合的航迹仿真方法,以准确描述刚体目标的运动规律。修正基于航迹的刚体目标姿态角计算方法,避免模型切换时的姿态角振荡现象,便于相关应用的实现。

Abstract: The characteristic orderliness of several typical tracks is analyzed, based on the theory of multi-track assembling, the 3D track is simulated by three kinds of basic state equations, aiming at the problem of the track smoothness in model changes, this paper proposes a track simulation way which is based on least-squares fitting, the motion of the rigid body is described accurately. It revises the way to obtain the pose angle of the rigid body target based on track, avoids the pose surge when the model changes, and it is a good reference for relevant applications.

Key words: rigid body, large amplitude maneuver, 3D track, pose angle, least-squares fitting
