摘　　要：介绍了采用载波相位测量方法进行相控阵波束时延标定的工作原理及测试方法,构建了外场测试环境,开展了波束时延测量。测量结果,表明载波相位测量方法的测量精度比伪距测量方法高出一个量级。通过载波相位测量数据,对影响测试结果的空间链路传输距离标定误差、转台臂长测量误差及信标天线指向误差进行了分析。The principle and measurements method on time delay calibration of phased array which adopts carrier phase measurements is introduced.The test environment is set up and the time delay measurement is carried out.Test results show that the accuracy based on carrier phase measurements is increased by one order of magnitude compared with the method of pseudo range.The factors which affect the carrier phase measurements result such as the calibration error of the distance,the measurement error of the turntable armlength and the directivity error of the beacon antenna are analyzed.
