数值研究了基于受激布里渊散射的微波多频信号测量的工作原理和性能。对未知信号进行特殊处理，产生一个增益区，通过相位调制到幅度调制的转换来测量。通过扫描矢量网络分析仪，可以实现单频和多频测量。其中一个泵浦产生的损耗谱被另一个泵浦的增益谱完全补偿，这将测量范围从2νB增加到4νB。
We numerically investigate the operational principle and performance of stimulated Brillouin scattering based multiple microwave frequency signals measurement. The unknown signals are processed specially to generate a gain region which is measured by phase modulation to amplitude modulation converting. By sweeping the vector network analyzer, both single and multiple frequencies measurement can be achieved. The loss spectrum generated by one of the pumps is fully compensated by the gain spectrum of the other pump, which increases the measurement range from 2νB to 4νB.
