Research groups

SCAN : Signal-Communication-Antennas-Navigation

The SCAN group is comprised of around twelve associate professors, professors and research engineers, who have extensive expertise in signal processing : adaptive antennas, radar processing, receiver architectures and communication techniques and networks applied to telecommunications, satellite constellation-based positioning and navigation (GNSS), GNSS receiver architecture based on FPGA.

Adaptive antennas

The group is involved in research activities in the field of adaptive antennas, from modeling and design of antennas, to array processing techniques.

Particular attention is paid to the analysis of the impact of their environment on antennas, as well as to the design and analysis of robust adaptive techniques for beamforming, detection and direction finding. The main applications are in the area of radar, communications and navigation.

Some specific projects include:

  • space-time adaptive processing (STAP) in non-homegeneous clutter for airborne radars,
  • adaptive radar detection in the presence of uncertainties about the space and/or time signature of the target,
  • robust adaptive beamforming,
  • beamforming for satellite communications with dispersed coverage,
  • array processing for multipath mitigation in GNSS systems,
  • wideband radar array processing,
  • multiscale and multiresolution techniques for the finite-difference, time-domain method (FDTD).

Navigation systems (GNSS and Multi-Sensor fusion)

The aim of these activities is to improve the performance of positioning and navigation systems in urban canyons, which represent an adverse environment for GNSS signals (poor GDOP, low C/No ratio, interference).

One of the research topics concerns mitigation techniques, using precorrelation processing inside the receiver or adaptive antenna arrays.

Another topic aims at defining a new approach for GPS/INS integration. These architectures based on low cost sensors (odometer, inertial sensors, image sensors) benefit from the laboratory’s experience in the development of complex systems.

This activity involves the following fields:

  • antenna processing for GNSS signals (supported by the adaptive antenna group),
  • secure navigation in urban environments,
  • non linear filtering technique for low cost navigation systems,
  • GNSS/MEMS inertial sensors integration,
  • reconfigurable in-space receivers for GNSS and TM/TC signals,
  • new air interfaces for navigation systems in S & C frequency bands.

SSPA: Space systems for planetology and its Applications

The focus of this team is to develop associated missions and technologies for geophysical exploration of the solar system.

Using physical modelling and experimentation, the development of payloads and space missions, the SSPA team strives to understand the internal structure and evolution of so called telluric planets.

The SSPA team works extensively on a partnership basis, internally with the complex system engineering department (DISC), the Department of Design and operation of aerospace vehicles (DCAS), the Mechanics of Structures and Materials Department (DMSM), as well as the ONERA via the Department of Models for aerodynamics and energetics (DMAE).

CIMI: Microelectronic image sensors

The research team has been working for many years, focusing on two main goals to improve the performance of CMOS imagers and to propose new architectures aimed at the development of new dedicated applications.

Several studies were performed in partnership with EADS-Astrium to define architectures of imagers dedicated to Earth observation from space in LEO or GEO orbits, that led to development of both silicon demonstrators and the COBRA2M 2D imager, which have been integrated into the GOCI (Geostationary Ocean Color Imager) observation instrument aboard a COMS (Communication, Ocean and Meteorological Satellite) satellite placed in GEO orbit in 2010. Photos taken by the sensor are available on kosc website (category COMS -> GOCI). Another result of these studies is the development program of the VNIR detector for ESA’s Sentinel 2 mission.
