High power microwave measurement based on microwave photonics

The high power microwave(HPM) measurement diagnoses technology is an important content of the study of HPM technology. For the realistic demand, the study found a measurement system using the microwave photonics technology, expatiating the elements of the system, and analysing the performance of the measurement system via simulation. The measurement system uses the ultra-wideband large-dynamic Mach-Zehnder-modulator and photodetector, uses the optical fiber to carry on the remote telecontrol measurement, thus to avoid the radiation and transmission interference, and finally the measurement bandwidth can be achieved 40 GHz and the spurious free dynamic range(SFDR) can be achieved 100 dB/Hz2/3.
