测温精度是衡量分布式光纤温度传感系统的一项重要性能指标.本文提出一种通过解调布里渊增益谱边带，以提高布里渊光时域反射仪测温精度的方法.在此基础上，进一步分析并验证了探测光脉冲峰值功率对测温精度的影响.理论分析表明，利用声光调制器的频移特性可产生布里渊增益谱边带，相比于中心峰解调方法，采用布里渊增益谱边带解调法可获得更高的系统信噪比，进而提高系统测温精度.实验结果表明，在相同测量条件下，布里渊增益谱左边带峰值功率较其中心峰峰值功率高3.27 dB，且其-1 dB谱宽比中心峰窄14.5 MHz.对布里渊增益谱左边带进行频率扫描，由于相干探测时参考光的作用以及消除了相干瑞利噪声的影响，系统信噪比提高了4.35 dB，并在10.2 km的传感距离上实现了0.5℃的测温精度.
