利用受激布里渊散射和非线性拟合，实验证明了一种多频微波测量方法。通过在受激布里渊散射过程中扫描参考频率，通过建立系统总输出功率与参考频率之间的映射关系来检测待测微波信号的频率信息。采用非线性拟合的方法，克服了布里渊增益谱线宽的限制，显著提高了测量分辨率。该方案实现了18 MHz的最小可分辨频率间隔，在21.42 GHz范围内测量误差小于5 MHz。该方法为在光子域实现对1190个频率左右的连续微波正弦信号的测量提供了一种有效的方法。
A multiple microwave frequency measurement is experimentally demonstrated by exploiting stimulated Brillouin scattering and nonlinear fitting. Through sweeping a reference frequency during the stimulated Brillouin scattering process, the frequency information of microwave signal to be measured is detected by the created mapping between the total output power of the system and the reference frequency. Nonlinear fitting is utilized to mitigate the limitation of Brillouin gain spectrum linewidth and the measurement resolution is improved significantly. The minimum distinguishable frequency interval of 18 MHz is realized with the proposed scheme, and the measurement error is less than 5 MHz with in a range of 21.42 GHz. This approach offers an effective way to implement the measurement on continuous microwave sinusoidal signal with a number of frequencies of about 1190 in photonics domain.
