摘要
介绍了对低轨卫星目标进行跟踪的一种实现方法,详细阐述了单脉冲差模跟踪接收机的工作原理,给出了接收机的原理实现框图,在实际工程应用中采集数据,并进行了跟踪误差分析。差模技术是现代天线角跟踪系统中的关键技术之一。该技术设计合理,工作稳定,特别是在低轨道遥感遥测卫星地面接收系统中得到了越来越广泛的应用,取得了较好的效果。
A method of tracking LEO satellite is introduced in this papor, a monopulse tracking receiving of defferential mode with emphasis on its oporation principle, and the implementation principle block diagram of receiver is given, tracking error is analyzed by sampling data on practial project. Differential mode technology is a key technique in antenna angle tracking system. Its design is reasonable and working is steady, so the tracking mode is playing a more and more important role in LEO remote sensing satellite receiving system, and has a significant effect.
