无人飞行器跟踪测角体制研究

Research on Tracking Angle Measurement System of Unmanned Aircraft

指出了无人飞行器测控系统中自跟踪测角设备的重要性。简要阐述了常用的相位干涉仪和单脉冲(单平面的比幅及比相)2种测角体制的原理,并给出了这2种测角体制的应用方案。进行了理论分析,从系统的测角精度及设备的复杂性等方面比较了2种体制的优缺点,为系统设计时如何选取合适的测角体制提供了依据。

This paper firstly points out the importance of self-tracking angle measurement equipment in the UAV telemetry ＆ telecontrol system, and describes briefly the principles of two angle measuring systems, one with phase interferometer, and the other with single pulse （amplitude comparison and phase comparison on a single plane）. Then this paper presents two application scenarios respectively for the two angle measuring systems and gives the theoretical analysis. The advantages and disadvantages of both systems are compared in terms of system accuracy and equipment complexity, providing basis for selection of appropriate angle measuring systems in engineering design.
