摘要
某型无人机的导引系统需要具备可靠、精密、可用等特点。文中首先对比了现行的三种导引系统,接着说明微波着陆系统(MLS)和所有的无线电测量系统一样,不可避免地存在系统误差。从微波着陆系统工作原理出发,分析讨论了角度测量过程中存在的误差源,及其所影响到的角度计算因子。进而给出了来自不同误差源的误差概算,最终结合系统测角精度要求,得出了相关设备的参数选择参考。
Like all wirelesses measurement system, MLS exists inevitably system error.This paper first discussed three main guiding system, and then, base on MLS principle, analyzed error sources as well as other factors that affect the measurement result. Finally, parameter selections were provided upon requirement of system accuracy of measurement.
