Offer Description

Satellite navigation (GPS and GNSS) is a key element for a multitude of applications (UAV, loitering amunition, guided projectiles, flying- road- or floating vehicles) ; the GNSS positioning and the timing are also absolutely required for a wide range of systems (as for Starlink for example. On the battlefield, the (sometimes intensive) usages of GNSS jammers and spoofers prevent, by their number, opposing systems to use the GNSS services. Beyond conflict zones, protection through low-cost systems of civilian vehicles or infrastructure seems to be today mandatory in a turbulent geopolitical context. The performance enhancement of interference mitigation system constitutes a major research topic.

Objectives :

In the field of GNSS radionavigation, this study aims to investigate and design antennas with radiation characteristic reconfigurability (typ. by analog function, with a limited number of states) to be associated with a signal processing unit and to constitute hybrid CRPA (analog/digital) with enhanced mitigation performances. The objectives are to reach higher rejection levels and to enable gain reduction in angular directions where the signal processing unit by itself can not address, because of a lack of sufficient acquisition channels.

Proposed work program :

Relyingonthepreviousworksandtheknow-howofISLandIETR,themainobjectiveofthisPhDsubject is the design of a reconfigurable antennas (diversity of radiation patterns, polarization, orientation, etc) wideband and multi-band for CRPA applications. This complete work can be divested asfollow:

• Investigation of potential antenna architectures with reduced gain in various angular sectors, then design of fixed radiation patterns antennas over a monoband and over multiplebands
• Integration into arrays of the designed antennas and radiation performance assessment as well as rejectioncapabilities
• Investigation of reconfiguration technologies: applications for monoband and multiband antennas. Prototypes will be manufactured and characterized. Then they will be associated to spatial filtering signal processing units in order to characterize the whole system in anechoic chamber but also in outdoor measurementcampaigns.
