Description du projet
Des technologies optiques susceptibles de nous aider à mieux «voir» avec les radars
Les radars ont parcouru bien du chemin depuis que le terme a été inventé pendant la Seconde Guerre mondiale: il s’agit en effet de l’acronyme de «RAdio Detection And Ranging». Il existe aujourd’hui de nombreux types de technologies radar disponibles ou en cours de développement, qui fonctionnent toutes sur le principe de l’émission d’un signal électromagnétique et de l’analyse du signal réfléchi pour la détection ou le suivi d’objets et l’évaluation de leur vitesse. Le projet Photonic Radar, financé par l’UE, développe un concept de radar hybride basé sur la photonique, qui utilise des lasers pour produire et analyser les signaux. Ce système avancé devrait améliorer la résolution et la précision des images et sera testé dans un système de transport intelligent.
Objectif
The conventional radar systems, operating in mm-wave (MMW) i.e. beyond 30 GHz, are exposed to high free-path losses (≥ 1 dB/km) and the situation becomes more punitive under severe environment conditions, for instance, Heavy rain and fog. Moreover, the traditional radar distribution networks are realized with conventional cables or space-feeds that results in a massive, complex and inflexible system. To overcome these issues, the hybrid photonic-based radar system (PHRAD) emerges as a promising candidate, providing low-loss, immunity to EM interference and high bandwidth capacity. These robust properties of photonics play a vital role in realization of PHRAD transceiver with improved navigation and detection. Although, the possibility of multiband PHRAD, capable to work in both S-and X-band, becomes feasible that reduces the weight, size and cost of the system. Alternatively, the state-of-the-art electronic techniques have not the required potential to make such radars feasible. The key goal of the proposed project is to develop a PHRAD transceiver tunable over a wide frequency range (≥ 40GHz) and immune to phase fluctuations in order to realize a robust navigation and detection system capable of providing high imagery-resolution and accuracy. The proposed work will be carried out in three phases. In phase I, Mode lock Lasers will be cultivated to generate wide-range and phase-stable radar signals in MMW. These wide-bandwidth signals (40-80GHz) will help to provide high imagery-resolution with accurate speed-computation of objects that lead to a reliable and secure navigation to the autonomous vehicles. In phase II, a multiband PHRAD transceiver will be designed to provide high frequency-flexibility that provides capability to track any frequency signal within S-or X-band. The phase III is dedicated to the implementation of the developed multiband PHRAD in real-time environment, especially in intelligent transport system (ITS), for its testing and evaluation.
