A novel coherent radar/lidar integrated architecture is proposed. It is based on previously published photonic-assisted radar and presents an innovative lidar scheme. The proposed lidar sensor exploits the same mode locked laser used for radar, minimizing the additional required hardware and power budget. Moreover an integrated radar/lidar system, merging the peculiarities of both the sensors, can...
This work shows the concept, performance, and field-trials of the first photonics-based radar. The comparative in-field experiments in aerial and naval scenarios against a state-of-the-art commercial system show the photonics potentials in enabling software-defined radars.
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.
The field trial results of the first photonics-based radar system in a real maritime environment are presented in this paper. The exploited prototype is the final outcome of the ERC-funded project PHODIR (PHOtonics-based fully DIgital Radar). The system exploits photonic technologies for both the generation and the detection of radar RF signals, allowing increased performance and an unprecedented...
In this paper we propose a photonic technique for a reconfigurable microwave signal generation based on the beating in a photodiode of two laser modes from a regenerative Fiber Mode-Locked Laser (FMLL). The excellent performance of this kind of pulsed laser guarantees high stability to the generated microwave signal even at ultra high frequencies (up to W band). Therefore, by using the proposed architecture,...
