Photonics in coherent multiband radar systems

The cross-fertilization between photonics and microwave systems is setting new paradigms in radar systems leading towards a new generation of multifunctional systems, able to manage multiple simultaneous coherent radio signals at different frequencies, enabling multispectral imaging for advanced surveillance systems. This paper present the first multiband photonics-based radar transceiver, reporting on the first demonstrator of fully coherent dual band radar.
