Abstract :
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.
