摘　　要：单脉冲跟踪体制下测控设备需要进行校相,传统校相依赖于标校塔。针对这个局限性开展了无塔校相方法研究。从和差双通道角度跟踪原理出发,介绍了无塔校相研究的最新进展,总结了三种无塔校相方法以及各种方法的应用条件。试验证明了这些方法的可行性,并且有些方法已进入工程应用阶段。In the monopulse tracking system, traditional phase calibration relies on the calibration tower. For avoiding this limitation, it＇s necessary to research the calibration method without tower. In this paper, based on the principle of sum- differential channel angle tracking, the recent progress in research of towerless phase calibration is presented, three methods and their application conditions are summarized. The experiment results show that these methods are feasible, some of which have been developed in engineering application.
