The field trial results of the first photonics-based fully digital radar system are presented. The system has been developed in the PHODIR project, and is tested here in a real aerial scenario with non-cooperative targets. The innovative radar is described, and the results are presented and discussed.
A novel solution for the optical generation of radio-frequency signals for coherent radars is proposed, which exploits the same mode-locking laser of the photonic-assisted radar receiver. The scheme, which is based on the concept of shifting the frequency of a laser mode, exploits a commercial optical in-phase/quadrature modulator to allow using a single mode-locking laser for both the radar transmitter...
A novel RF-generating scheme exploits a commercial optical I/Q modulator to allow using a single mode-locking laser for both radar transmitter and receiver, making the solution attractive for immediate and practical implementation in photonics-assisted transceivers.
A supercontinuum-based multiwavelength laser is proposed and tested in a realistic WDM-PON scenario. BER comparison with commercial multiple channel laser array confirms this multiwavelength laser as a strong candidate for WDM-PON applications.
A characterisation of a SOA-based modulation suppressor for 10 Gb/s RZ and NRZ signals is performed. Its effectiveness in colourless WDM PON is demonstrated obtaining error-free operation in a 20 km-long link.
