  • vision based augmented reality for pilot guidance in Airport Runways and taxiways
    International Symposium on Mixed and Augmented Reality, 2004
    Co-Authors: J Molineros, Reinhold Behringer, C Tam
    Abstract:

    This paper describes our on-going efforts to develop an augmented reality system for enhanced pilot situational awareness in Airport Runways and taxiways. The system consists of a sensing component based on computer vision and an information component based on high-fidelity graphic model databases. Vision algorithms are used for a variety of guidance and warning tasks. A necessary requirement is for vision algorithms to have a real-time response.

  • 90 GHz - 3D Scattered Field Measurements for Investigation of Foreign Object Debris
    IEEE Transactions on Antennas and Propagation, 2019
    Co-Authors: Florence. Nsengiyumva, Carla Migliaccio, Jerôme Lanteri, Jean-yves Dauvignac, Laurent Brochier, Ch Pichot
    Abstract:

    Scattering properties of millimeter waves (MMW) remain relatively unknown compared to lower frequency bands, although their study is of interest considering the increasing number of civil applications, especially in the W-band. In this paper, we present an efficient measurement set-up that provides scattering measurements with spatial and polarization diversities. The targeted application is Foreign Object Debris (FOD) detection and identification for surveillance of Airport Runways. Most existing systems are monostatic but rapid advances in MMW technology pushes toward the deployment of multistatic radars on either side of Airport Runways. In the following, we investigate the contribution of multistatic measurements with a special focus on the reconstruction of glass and brake pad debris, courtesy of DGAC (French Civil Aviation). We also present an efficient approach for making images of FODs. For this, we process scattered field measurements with an additive (with respect to polarization) back-propagation algorithm. First images include all measured points taken from the upper hemisphere. In order to get closer to the final application, we restrict the field of view to receivers facing the transmitter. Both approaches provide very good shape reconstruction of the glass debris and the central zone of the brake pad. To our best knowledge, this is the first time that full-3D measurements have been conducted on FODs in the W-band. It is also the first example of a 3D qualitative image of FOD obtained from measured data in the W-band

  • Millimeter-Wave Imaging for FOD Detection
    Air Traffic Management and Systems III, 2019
    Co-Authors: Florence. Nsengiyumva, C. Migliaccio, Ch Pichot
    Abstract:

    We present an efficient approach for reconstructing images of small objects and Foreign Object Debris (FODs) from scattered field synthetic data and measurements in W-band (75−110 GHz), taking advantages of spatial and polarization diversities, and process them with either qualitative or quantitative inverse methods. The target application is FOD detection for Airport Runways. We investigate FOD detection and identification capabilities through two approaches: a quantitative reconstruction under 2D assumption and qualitative reconstruction using a Backpropagation algorithm (BP). Most existing systems are monostatic but rapid advances in millimeter-wave technologies make it realistic to imagine the deployment of multistatic radars on either side of Airport Runways. In the following, we investigate the contribution of multistatic measurements, on the reconstruction of typical debris, courtesy of DGAC (French Civil Aviation).

  • Detection of Debris (FOD) on Runways in W-Band: Relevance and Validity Domain of Two-Dimensional Approaches
    2015
    Co-Authors: Florence. Nsengiyumva, Ch Pichot, Jerôme Lanteri, Ioannis Aliferis, Carla Migliaccio
    Abstract:

    For sake of simplicity and execution speed, many imaging algorithms are based on two-dimensional approaches. We present a study on the relevance and validity domain of two-dimensional approaches to detect debris on Airport Runways in W-band (75-110 GHz), taking into account polarization (both 2D-TM and 2D-TE). The study deals, first with objects in free-space, and second placed on runway in far field configuration using plane wave illumination or horn antenna.

  • 76.5 GHz millimeter-wave radar for foreign objects debris detection on Airport Runways
    International Journal of Microwave and Wireless Technologies, 2012
    Co-Authors: Karim Mazouni, Armin Zeitler, Carla Migliaccio, Jerôme Lanteri, Ch Pichot, Naruto Yonemoto, Akiko Kohmura, Jean-yves Dauvignac, Shunichi Futatsumori
    Abstract:

    The paper is a joint work between the LEAT (France) and the ENRI (Japan) in the framework of a Sakura project supported by the JSPS and the French Ministry of Foreign Affairs. The purpose is the study of a FOD (Foreign Object Debris) detection system on Airport Runways. An FM-CW mm-wave radar working between 76.25 and 76.75 GHz is used together with a high directivity printed reflectarray. In addition, a second measurement campaign has been conducted with a 73.8–79.8 GHz (6 GHz band) radar. Measurement results show detection capabilities of a −20 dBsm cylinder up to 35 m that is 10 m less than the FAA recommendations. Antenna improvements are discussed for reaching the requirements and system performance as well as the use of calibration objects.

  • Climate change impacts on critical international transportation assets of Caribbean Small Island Developing States (SIDS): the case of Jamaica and Saint Lucia
    Regional Environmental Change, 2018
    Co-Authors: Isavela Ν. Monioudi, Regina Asariotis, Austin Becker, Cassandra Bhat, Danielle Dowding-gooden, Miguel Esteban, Luc Feyen, Lorenzo Mentaschi, Antigoni Nikolaou, Leonard Nurse
    Abstract:

    This contribution presents an assessment of the potential vulnerabilities to climate variability and change (CV & C) of the critical transportation infrastructure of Caribbean Small Island Developing States (SIDS). It focuses on potential operational disruptions and coastal inundation forced by CV & C on four coastal international Airports and four seaports in Jamaica and Saint Lucia which are critical facilitators of international connectivity and socioeconomic development. Impact assessments have been carried out under climatic conditions forced by a 1.5 °C specific warming level (SWL) above pre-industrial levels, as well as for different emission scenarios and time periods in the twenty-first century. Disruptions and increasing costs due to, e.g., more frequent exceedance of high temperature thresholds that could impede transport operations are predicted, even under the 1.5 °C SWL, advocated by the Alliance of Small Island States (AOSIS) and reflected as an aspirational goal in the Paris Climate Agreement. Dynamic modeling of the coastal inundation under different return periods of projected extreme sea levels (ESLs) indicates that the examined Airports and seaports will face increasing coastal inundation during the century. Inundation is projected for the Airport Runways of some of the examined international Airports and most of the seaports, even from the 100-year extreme sea level under 1.5 °C SWL. In the absence of effective technical adaptation measures, both operational disruptions and coastal inundation are projected to increasingly affect all examined assets over the course of the century.

  • 77 GHz offset reflectarray for FOD detection on Airport Runways
    International Journal of Microwave and Wireless Technologies, 2012
    Co-Authors: Karim Mazouni, Carla Migliaccio, Shunichi Futatsumori, Jerôme Lanteri, Ch Pichot, Akiko Kohmura, Jean-yves Dauvignac, Naruto Yonemoto
    Abstract:

    In designing a Foreign Object Debris (FOD) detection system on Airport Runways, this paper deals with the performance of a 77 GHz reflectarray antenna (RA). Debris may be very small and have low radar cross section (RCS), leading to design a high gain primary-fed offset RA. To minimize the aperture blockage, the main radiation lobe is in the specular direction. The antenna has a maximum gain of 40 dBi and aperture efficiency of 50% over the frequency band 76–77 GHz. First measurements using a 77 GHz radar module were carried out on pavement.
