摘要
单通道单脉冲角跟踪技术因其精度高、工作信噪比较低、动态响应快以及实现简单、可靠,在无人飞行器测控领域得到广泛应用。通过分析单通道单脉冲扩频角跟踪技术的工作原理,给出了该技术在工程中的实现方案;同时考虑到工程应用中的具体需求,对传统的解扩方法进行了改进,以适应单通道单脉冲扩频角跟踪技术在无人飞行器测控领域的应用。
The technology of single channel monopulse（SCM） angle tracking is widely applied in unmanned aerial vehicle（UAV） TTC for its high accuracy,lower signal to noise ratio of operation,fast dynamic response and simple implementation and reliability.By analyzing the principle of spread spectrum SCM angle tracking,the method of engineering implementation is given;meanwhile,considering the specific requirements of engineering application,the traditional de-spreading method is improved for the application of SCM angle tracking in UAV TTC.
