提出并演示了一种同时测量多个微波信号的频率和功率的光学方法。该系统基于对干涉图的处理，该干涉图是通过在可调谐光子微波陷波滤波器的输出处对测量频带上的微波功率进行积分而生成的。提供了演示工作原理的实验结果，显示分辨率为 15 MHz。
An optical approach to simultaneously measure the frequency and power of several microwave signals is presented and demonstrated. The system is based on the processing of an interferogram generated by integrating the microwave power over the measurement band at the output of a tunable photonic microwave notch filter. Experimental results to demonstrate the principle of operation are provided showing a resolution of 15 MHz.
