 Title : Artificial Intelligence in Radars

 Abstract : Antenna digitalization will increasingly enable to design full software-defined radars with more degrees of freedom (scalable front-end, digital beamforming with diverse beam shapes…), enhanced with intelligent resource management and graceful degradation by reconfiguration. Radars will become proactive to achieve more complex missions. They will integrate digital assistants to interact with human operators through intuitive multimodal dialogue.

Artificial Intelligence (AI) algorithms (optimization, learning, reasoning…) will foster the development of cognitive functions underlying innovative capabilities as self-adaptation, contextual inference and situation understanding. Coordinated in dense networks, radars will be able to optimize their resources in a collaborative way, potentially fully distributed, with advanced “what-if” capabilities to improve their agility and robustness to defeat new threats (hypersonic & hyper-maneuvering missiles, swarm of drones, stealth mobile objects, slow moving targets…). Such AI-based functions will help improve operational capacity in tactical anticipation.

As a result of radar’s full digital transformation, the radar's digital twin will enable to faster prototyping, algorithm design and AI-based augmented engineering. Thales TrUE AI (Transparent, Understandable and Ethical AI) strategy for a trustable and explainable AI will be also implemented in radar systems. Relying on a hybrid AI (combining model-based and data-driven approaches), it aims at paving the way to the design, the development, the validation and the certification of critical systems involving AI technologies.

 Title : Radar Technical Challenges, from decameter to centimeter wavelengths.

 Abstract : ONERA has been involved and remains a major actor in the field of decameter wavelengths radars. In parallel to operating the NOSTRADAMUS sky-wave radar, it has developed several demonstrators of HF surface wave radar in multiple sea shore sites. In regards to the airborne radars, the metric to centimetric radars, on board of the SETHI station, they offer a large variety of applications such as detection through ice, the environmental measurements or the testing of new methods of analysis applied to surveillance. All these radars have in common the benefits engendered by the power of combining new or updated old technologies, therefore significantly increasing their performances in different domains such as full digital radar, multistatism, increased computing power of simulation, deep learning coupled with physical models, advances in metamaterials, carriers diversification impacts or artificial intelligence... Examples drawn from the latest research conducted at ONERA will help illustrate this strong trend.

Title : Seas of radar opportunities

Abstract : Indeed, there are many opportunities for satellite RADAR over water surfaces from low to high resolution, based on radar cross-section (NRCS) and/or Doppler, with low or high precision and in both operational or research stages. Generally, geophysical requirements for earth observation (EO) are coupled to technical challenges.
Sea level, wave height, storm surges and tides are part of operational radar applications through satellite altimeters, which are being further developed, e.g., through the EU Sentinel-3. Similarly, ocean vector wind, wind stress and wave variables have resulted in operational applications, in addition to oil spill detection by Synthetic Aperture Radar (SAR). Challenges with respect to calibration and spatial processing have been overcome, leading to very accurate, detailed and stable geophysical retrievals. Ongoing technical challenges for earth system modelling at the atmosphere-ocean interface exist in ocean motion, ocean current and bathymetry measurements, in particular in coastal areas. Some of these many challenges will be elaborated at the conference.

 Title : High-Resolution Radar Signal and Information Processing

 Abstract : High-resolution radars utilize wide-band signals to achieve high range resolution and employ synthetic apertures to achieve high angle resolution. They classify and identify targets precisely by providing multi-dimensional high-resolution images with target feature information. High-resolution radars allow more applications of advanced signal processing algorithms to focus on target classification and precise recognition. Under clutter and interference conditions, high-resolution radars offer unique advantages in target detection and tracking. However, these advantages are limited by factors such as reduced radar detection range, complex radar signal processing, and exceedingly huge amount of data, posing problems in urgent need of theoretical and methodological innovations for their solution. In this perspective, this talk introduces the latest research on high-resolution radar signal and information processing in Radar Research Lab, Beijing Institute of Technology (BIT). The research mainly focuses on the detection theories, technical breakthroughs and applications in one-dimensional high-resolution ground-to-air, air-to-ground radar and high-resolution distributed radar.

 Title : Artificial electric sense for underwater robotics: state of the art and perspectives

 Abstract : Fish that can electrocute their prey have been known since antiquity and inspired Volta to design the first battery. However, the ability of other so-called weakly electric fish to perceive their near surroundings by sensing through a dense array of transcutaneous electroreceptors the perturbations of a self-generated electric field, was only discovered in the 1950's. Remarkably, these fish are able to detect, localize and analyze objects in confined environments and turbid waters, where neither vision nor sonar can work. Named Active Electrolocation by biologists, this perceptual ability recently has drawn the attention of roboticists with the aim of designing a novel generation of underwater robots able to navigate and operate in harsh environmental conditions. In this perspective, this keynote attempts to give a comprehensive overview of the recent progresses in artificial e-sense for underwater robotics. Starting from the fish, we will progressively move toward robotics and address several issues ranging from reactive autonomous navigation, localization and shape recognition, to haptic feedback teleoperation. While progressing, we will attempt to reveal further insights on how nature can inspire engineering.

 Title : 100kg-class X-band Synthetic Aperture Radar Satellite System for On-Demand Observation

 Abstract : During emergency situations such a natural or man-made disaster, rapid responses by social infrastructure are essential in order to minimize damage.
The Cabinet office of Japan has funded a technology-driven innovation program, “ImPACT,” which stands for “Impulsing Paradigm Change through Disruptive Technology Program.” Under the ImPACT program, we developed the key technology of Small Synthetic Aperture Radar (SAR) satellite system capable of on-demand launching and quick observation from FY2015 to FY2018. Our aimed system enables“ all-time and all-point observation” in whole world under all condition, even at night and under rainy/cloudy/stormy weather. There are two keys of this program. One was to realize achieve the compact SAR, selection of deployable and passive slot array antenna approach rather than the two major methods used worldwide (active phased array antenna system approach and parabola antenna system approach) to achieve the world’s most lightweight, most compact SAR system. The other one is to realize achieve instant, on-demand observations, achievement of an autonomous operation. The new approach of SAR design” realizes an ultra-lightweight and highly compact, 100kg-class, satellite system with 1m-class spatial resolution SAR sensor. Considering future business prospects, the mass production cost around 5 million dollar is targeted in this program, which will be one-tenth of conventional systems.
For the social implementation of this technologies, we set up a start-up “Synspective”. We will launch the first demonstration satellite in this fiscal year. And we will launch six satellite in three yesars.
