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。
Under the current operating mode of the answering machine antenna system, the rotation of the aircraft causes its antenna beam direction to change constantly, resulting in the discontinuity of the signal of the ground monitoring and control equipment, the inability to obtain continuous measurement data and the difficulty of accurate tracking measurement. Aiming at the problem of rotation measurement, this paper designs a diversity answering machine antenna system. The theoretical analysis and simulation results show that the system can effectively solve the shortcomings of the existing antenna system and achieve continuous and stable tracking of the rotary vehicle .
