摘　　要：地面测控系统中,常用的跟踪体制为比幅单脉冲跟踪体制,不论是单脉冲单通道还是单脉冲双通道跟踪体制,其首先要解决的是校相问题,通过校相保证和、差通道相位一致性,才能实现对目标的稳定跟踪。本文主要介绍了应用于地面测控系统中的校相技术,包括对塔校相、对星校相、对射电星校相、近场校相等方法以及无人机在校相技术中的应用,总结了各种方法的基本原理及使用方法。In TT&C system,monopulse single channel and dual-channel tracking receiver are often used.Phase calibration is the priority to be considered in angel tracking system.In order to maintain stable tracking status,the difference of phase between sum channel and differential channel are must be calibrated.In this paper,several phase calibrtion methods are introduced,including tower phase calibration,stallite phase calibration,raido star phase calibration,near field phase calibration and unmanned aerial vehicle.These methods are often used in engineering projects.The principles and usage methods of these ways are introduced in this paper.
