摘要:
基于传统参考点导引方法standoff模式进行目标跟踪,当无人机相对目标速度方向与无人机在圆形期望航迹上对应点的切线方向夹角接近90°,且接近期望航迹时,存在无人机收敛到圆形期望航迹上效率不高的问题。根据线性化参考点法跟踪圆形期望航迹的小角度假设,设计了基于参考点法的无人机standoff跟踪固定/移动目标机动飞行进入导引策略。仿真验证了该策略的有效性,使无人机能快速收敛到跟踪目标的圆形期望航迹上。

Guidance Strategy for UAV Tracking Target Based on Reference Point Guidance Method

Abstract:
When the target is tracked based on the current traditional reference point guidance method by standoff mode, if the angle between the relative speed of the UAV and the target and the tangential direction of the corresponding point on the circular expected flight path of UAV is close to 90 degrees, and UAV is close to the desired path, the efficiency of the UAV converging to the circular desired path is not high enough. In this paper, the small angle hypothesis for reference point guidance method tracking desired circular path is studied. According to this, we designed a maneuvering entry guiding strategy for UAV standoff tracking fixed/moving target based on reference point guidance method. Simulation results show effectiveness of the guidance strategy. UAV might quickly converge to the circular desired path.
Key words:    UAV    reference point guidance    standoff tracking    guidance strategy    moving target    simulation
