最近几年里,混杂信号(Sophisticated)雷达和通信系统的出现,及其对微波元件方面的要求,推动了微波相位测量技术的发展。快速电子扫描相控阵和脉冲压缩雷达的发展使有源的和无源的射频元件的相位传输特性显得更为重要了。在某些情况下要求测量精度必须提高 In recent years, the advent of Sophisticated radars and communication systems and their demands on microwave components has driven the development of microwave phase measurement techniques. The rapid development of electronic scanning phased array and pulse compression radar makes the phase transmission characteristics of active and passive RF components even more important. In some cases the accuracy of the measurement must be increased
