一种旋转飞行器应答机天线系统的设计

A Responder Antenna System Design for Spinning Spacecraft

在当前应答机天线系统的工作模式下,飞行器旋转会引起其天线波束方向不断变化,导致地面测控设备信号间断,不能获取连续测量数据,难以实现精确跟踪测量。针对旋转测量存在的问题,本文设计了一种分集式应答机天线系统,理论分析和仿真结果表明,通过采用该系统,有效解决了现有天线系统的不足,能够实现对旋转飞行器的连续稳定跟踪。

Because of the aerocraft＇ spinning flying,the current working pattern of responder antenna cannot provide continuous signal cover area,thus resulting in the discontinuous working of the radar measurement system and the failure of tracking.To solve this problem,in the article,a kind of design of diversity transponder antenna system is presented,which can provide dynamic continuous signal coverage.The theory analysis and simulation results show the validity of this design.
