摘　　要：特殊的动态条件决定了无塔标校方法是远洋测量船测量雷达进行海上跟踪链路相位标校的唯一选择。总结我国测量船以往使用的方法,其思路均是立足于寻找一个稳定的源去模拟标校塔,进而得到稳定的相位或相位差。但是随着我国航天事业的发展,加上海上固有的动态环境,此种思路已无法满足越来越高的指标要求。从相反的方向入手,分析校相过程引入误差的原理,再结合滤波手段,将不稳定因素滤除,进而得到不稳定条件下的稳定正确相位。The special dynamic condition decides that the towerless calibration method is one of the only option of the ocean-going tracking ship to carry on tracking link phase calibration.Summarizes methods which tracking ship formerly used,their mentality is bases in seeks a stable source to simulate the calibration tower,then obtaines the stable phase or the phase difference.But along with our country astronautics enterprise development,and the marine inherent dynamic environment,this kind of mentality has been unable to satisfy the more and more high target request.From the opposite direction,the error principle of the calibration process is analysed,and combined the filter method in addition,maked the unstable factors filtration,then obtained the stable correct phase under the unstability conditions.
