Title: Applications of Signal Detection and Estimation in Radar Systems

Abstract : In our daily life, we are constantly making decisions. Given some hypotheses, a criterion is selected, upon which a decision has to be made. In engineering, when there is a radar signal detection problem, the returned signal is observed and a decision is made as to whether a target (signal) is present or absent. At the receiver, the received signals are corrupted in the medium by some additive noise and by the receiver noise. The receiver does not know which part is signal and which part is noise but must make a decision to discriminate the signal form the noise. The process that the receiver undertakes in selecting a decision rule falls under the theory of signal detection. Assuming that the receiver has made a decision in favor of the true hypothesis but some parameter associated with the signal may not be known. The goal is to estimate those parameters in an optimum fashion. This falls under estimation theory. In practical radar signal detection systems, the problem is to automatically detect a target in thermal noise plus clutter. Clutter is a term applied to any unwanted radar signal from scatterers that are not of interest to the radar user. Since the environment in which the radar operates depends on factors such as weather conditions and the physical location of operation the returned signals are statistically nonstationary with unknown variance at the receiver input. Thus advanced signal processing with adaptive detection techniques are necessary to obtain “good” system performance. We present some of the applications of signal detection and estimation in different radar systems. Some advances and future perspectives in radar systems will be discussed. The impact of such an engineering field on the society, whether civilian or military, and on the security of a country will be mentioned briefly.

Title: Passive Radar Overview

Abstract : There has been a growing interest in passive sensing that exploits radio frequency (RF) wireless communication and broadcast signals as illuminators to detect, locate, and track objects of interest. Such passive RF sensing capabilities resemble radar functions but exceed the scope of standard radar operations. A typical radar is an active RF sensing system that requires a dedicated transmitter. In contrast, a passive radar hitchhikes existing wireless communication and broadcast sources, which are referred to as illuminators of opportunity (IOs), to probe the surveillance area. Specifically, many IOs are available for passive sensing, from analog FM radio and TV sources to digital sources such as cellular, digital audio/video broadcasting (DAB/DVB), GNSS, WiFi, and WiMAX signals. Passive radar enjoys a number of advantages over its active counterpart. A conventional active radar system usually has a single transmitter, whereas a passive system can simultaneously access several IOs and obtain multiple views of the surveillance area from different perspectives. Passive radar is also far more economical than its active counterpart since there is no transmitter related cost (construction, deployment and operation). Recent interest in passive radar is further driven by spectrum scarcity and a growing pressure from the wireless sector to release government-held spectrum, including spectrum allocated to active sensing, in order to boost the economy. Nevertheless, there are technical and non-technical issues that need to be addressed to fully realize the potential of passive radar. One urgent research direction is to develop a systematic signal processing framework specifically tailored for passive radar. Another issue is the low range resolution in radar imaging and ground clutter suppression. IO waveforms have a narrow signal bandwidth (typically from several MHz to tens MHz) as compared to that of nominal active radar systems (from hundreds MHz to a few GHz); hence passive radars suffer from a low range resolution which leads to undesirable performance in various applications. This talk is aimed at providing a comprehensive discussion on passive radar, including potential solutions to the issue discussed earlier, along with examples of recently fielded systems and measurement campaigns.

Title: Detection of covert communications over ununtrusted channels

Abstract : The possibility of covert channels and information hiding (steganography) within other pieces of information is becoming increasingly important in many applications such counter-terrorism, undetectable communications in battle fields etc. Covert channels and/or undetectable information hiding could be created in apparently innocuous phone calls and in video transmissions such as Skype calls over the net. Although, steganography can help address these problems to some an extent yet the technology often fails since it is based on camouflaging data as detectable noise by slightly altering digital data (audio/image/video). Any alteration may raise suspicion thus making hidden message discernable by simply computing its corresponding noise level. Adaptive steganography where the sender selects the location of data (pixels for an image) that will carry the message bits can be an attractive solution. This principle is similar to the known “writing on wet paper” metaphor. This metaphor can be explained as follows: suppose that an image is exposed to rain and that the sender can send a message by slightly modifying the dry spots of the cover image (but not the wet ones) to obtain a stego image. After transmission process, the stego image will drys out thus making the recipient incapable of knowing which pixels were used to hide information. This concept is useful since it allows the sender to have complete control/freedom to choose the pixels that will carry information and as such the sender may be able to formulate his/her rule of pixel selection that is not available to recipients and attackers thus leading to a much increased security than existing steganographic algorithms. So far the “writing on wet paper” is only a concept and has not been mathematically proven nor statistically analysed in terms of known performance metrics. Any digital object, such as image, video, sound, text document, can be used as a message carrier. Among all, digital video has advantages as a steganographic message carrier because motion can be a very useful means for carrying and hiding communications. In addition, the escalation of number of internet users, the advancements in networking infrastructures and improvements in social networking facilities, video streams have become the fastest growing traffic on the Internet and it is believed that currently video occupies over a quarter of internet traffic. As a result, the importance of video steganalysis is fast becoming an important application especially for the detection of clandestine and unhelpful communication. One of the most distinctive features of this seminar, Professor Bouridane will cover covers a number of data hiding tools and methods and their deployment in security problems including recent advances in perceptual hashing and digital hiding and their detection from digital multimedia data over unsecure channels such as internet.

Title: Quantum Technologies: the Second Quantum Revolution

Abstract : Quantum information technology is an interdisciplinary field of research which brings together quantum physics, photonics, electronics, nanotechnology, computer science, and information theory. Quantum information technology breaks limitations of conventional information transfer, cryptography and computation by using quantum superposition or entanglement as resources for information processing. These emerging technologies, at their core, all require reliable quantum devices, such single photon source, single photon detector, and quantum gates. Here, I will review this research field by covering multiple topics: quantum key distribution, secret sharing, detectable Byzantine agreement, clock synchronization, and reduction of communication complexity, and quantum computing.

Title: La Vision Industrielle : Une Technologie -clé de l'Industrie 4.0

Abstract : Dans un essor considérable, l'informatique ubiquitaire ne cesse de s'introduire dans des pans entiers de la vie sociale et économique de l'homme moderne. Ayant reconnu les prémisses et les challenges d'un « nouveau monde », mais aussi l'immense opportunité qui s'offre à l'innovation, au progrès et à la croissance, les pays industrialisés s'affairent au développement de stratégies idoines pour faire face aux changements drainés par ces technologies numériques en pleine effervescence. L'Allemagne élabore actuellement le concept de l'Industrie 4.0. Il consiste en l'exploitation intelligente des instances actives dans la production industrielle. Le concept se base sur une intégration dense des technologies de pointe à tous les niveaux de la chaîne de valeur ainsi que leur connexion à des réseaux de communication permettant le traitement et l'échange quasi instantané des informations. Ainsi seront optimisées les ressources nécessaires à la production et augmenté le degré de compétitivité. Au coeur de l'Industrie 4.0 se situe l'usine intelligente (smart factory). Dans l'industrie d'emballage à titre d'exemple, le travail jusque-là manuel est désormais effectué par des robots intégrés dans des chaînes de production. Ils sont équipés de systèmes de vision leur permettant de reconnaître les objets qu'ils auront à manipuler. Chaque produit est saisi individuellement, analysé compte tenu des spécifications prédéfinies et traité en conséquence. Les informations recueillies sur la quantité et la qualité des produits sont collectées continuellement et communiquées vers les instances supervisant les processus de production, si nécessaire en temps réel. De l'efficience des systèmes de vision, de leur fiabilité et leur robustesse dans l'environnement industriel, ainsi que de leur flexibilité à s'adapter aux changements afférents et aux fluctuations du marché dépendra la compétitivité, voire même l'existence de l'entreprise. Seront présentées diverses applications de la vision associée à la robotique industrielle émanant de différents domaines tels que l'industrie agro-alimentaire, pharmaceutique etc.

Title: Bornes Inférieures de l’Erreur Quadratique Moyenne : De la Théorie à la Pratique

Abstract : Un des objectifs du traitement du signal est l’extraction d’informations pertinentes cachées dans un jeu d’observations/de mesures bruitées. Ces informations ou paramètres d’intérêts peuvent être : une fréquence Doppler, une phase, une direction d’arrivée, etc. La théorie de l’estimation offre un cadre formel pour résoudre ce type de problèmes. Plus particulièrement, en estimation dite paramétrique, on se fixe un modèle d’observation dépendant des paramètres d’intérêts et, à partir d’une règle d’estimation basée sur ce modèle, on estime les paramètres d’intérêt. La règle d’estimation, qui conditionne les performances d’estimation, constitue la pierre angulaire du traitement du signal moderne et l’Erreur Quadratique Moyenne (EQM) est son indicateur de performance. Malheureusement, l'évaluation analytique exacte de l’EQM est souvent impossible à faire, sauf pour des cas très particuliers.

Une alternative consiste à trouver une limite inférieure de la variance (minimale) qu’un estimateur non biaisé peut espérer atteindre, et ce pour un modèle paramétrique donné. La connaissance de cette limite de performance est d'une grande importance car, non seulement elle permet de porter un jugement sur les performances d’un estimateur mais elle permet également i) de savoir si, à partir d'un estimateur particulier, une amélioration est possible, ii) de savoir si dans un contexte donné, il est possible de respecter certaines exigences fixées par un cahier des charges, et enfin iii) de concevoir/ dimensionner un système afin d'obtenir la meilleure précision possible.

Ce tutoriel fournit un aperçu complet de l'état-de-l’art sur les bornes inférieures de l’EQM. Les fondements théoriques, des exemples de dérivations et de calculs de ces bornes ainsi que des études de dimensionnement/conception de systèmes de capteurs seront présentés. Un accent sera mis sur les applications dans le domaine du radar et du traitement d’antennes.
