提出一种基于时钟同源I/Q解调的相位敏感光时域反射系统解调方法.分析了调制信号与混频信号非同源不一致对解调结果的影响，采用声光调制器调制信号、斩波信号与I/Q混频信号时钟同源的方法以消除残余频率的影响.实验采用双压电陶瓷作为扰动源，通过I/Q解调实时获得后向瑞利散射光幅值和相位，进而实现扰动的定位和还原.实验结果表明，该系统能有效地探测到5 km和9 km处的正弦扰动，定位信号信噪比分别达17.8 dB和16 dB，相位解调结果准确还原正弦扰动，与正弦曲线的拟合系数分别为0.994和0.991，均方根误差分别为0.116和0.141.实验进一步验证了该方法能够测得不同扰动幅度下的相位正弦变化曲线，并能准确得到不同扰动频率，且扰动位置处相位变化幅度与扰动强度具有良好的线性关系，线性拟合系数达0.992，均方根误差为0.499，均优于非同源解调结果.
