摘要

For high-speed wireless communication, the Internet, new-generation radar system and real-time signal processing system, microwave measurement systems with a large instantaneous bandwidth (greater than 10GHz) and wide working frequency range (several MHz to several hundred GHz) are required. To meet these demands, a simple and novel optical approach to implementing the broadband measurement approach is proposed. In the experiment, the Doppler frequency shifts are estimated with clear direction discrimination and high resolution with the max error of 8 Hz. Then, the approach is applied for phase detection, and the phase shifts are successfully measured and estimated for microwave signals with the operating frequency ranging from 10 to 40 GHz. The max error of phase measurement is calculated to be less than 7 degrees. The approach is simple, easy to implement, multifunctional and tunable, so that it can provide a more competitive approach to realizing the measurement of the microwave signals for future wideband electronics applications than electronic solutions.
