摘要
探月返回器再入段目标角动态大,可见弧段短。针对该问题,分析返回器再入目标捕获难点及关键技术,利用多波束测控系统波束指向控制灵活迅速的特点,通过对空域成像覆盖、捕获时间及流程设计进行研究,可以完成多波束同时覆盖预定空域进行目标搜索、大范围高动态目标的快速检测和捕获跟踪,从而实现探月返回器再入搜索捕获。仿真结果表明,所提方法能够实现信号快速检测,完成大动态目标角捕获以及大动态弱信号的快速捕获。
The target angle of lunar return vehicle in reentry phase is high dynamic,and the visible time is short.Aiming at this problem,the difficulties and key technologies of reentry target capture of the return vehicle are analyzed,and the characteristics of flexible and rapid beam-pointing control in multi-beam measurement and control system are used,and the airspace imaging coverage,capture time and process design are studied.The multi-beam simultaneous coverage of predetermined airspace for target search,rapid detection,tracking and capture of large-scale high dynamic target can be completed,so as to achieve reentry search and capture of lunar return vehicle.The simulation results show that the signal can be detected quickly,the high dynamic target angle capture can be completed and the high dynamic and weak signal can be captured rapidly using the proposed method.
