摘要 分析了ATP跟瞄相机的探测采样频率、闭环信号延时对ATP系统带宽的影响,并在此基础上,提出了高采样频率和低闭环延时的高带宽设计思路,设计并实现了高带宽ATP跟踪系统。仿真分析和试验测试结果表明:使用该跟瞄相机的ATP系统的干扰抑制带宽约为200Hz;在给定的输入条件下,系统跟瞄精度优于±1urad,能够满足星地量子通信的需求。 A design of a high-bandwidth ATP camera is proposed, and the high-bandwidth ATP camera is designed and implemented. Simulation analysis and experimental test results show that: with the ATP camera, the ATP system has a interference rejection bandwidth of about 200Hz and an accuracy of 1μ rad under given conditions, meeting the needs of quantum communication between satellite and the ground.
