摘　　要：讨论了连续波转发器设备时延 (距离零值 )测量技术 ,重点研究了利用测量副载波调制边带侧音相位完成中频调制转发应答机绝对距离零值测量的工作原理 ,并介绍了适用于各种形式应答机(包含中频调制转发应答机 )的距离零值通用测量方法 ,分析了测量方法误差。The Equipment Time-Delay (ETD) measurement technology for Continuous Wave (CW) transponder is discussed with emphasis on the principle of measuring the ETD of the intermediate frequency (IF) modulation transponder through measuring subcarrier modulation sideband tone phase. A general method for measuring ETD of different types of transponder (including IF-modulation transponder) is introduced. Finally the measurement method error is analyzed.
