In recent years, advances in radio detection and ranging technology, sustained by new achievements in the fields of signal processing and electronic components, have permitted the adoption of radars in many civil and defense applications. This resource discusses how highly integrated radar has been adopted by several new markets such as contactless vital sign monitoring (heart rate, breath rate) or harbour traffic control, as well as several applications for vehicle driver assistance. You are provided with scenarios, applications, and requirements, while focusing on the trade-offs between flexibility, programmability, power consumption, size and weight, and complexity.

The book presents the analysis and design of integrated automotive radar receivers in Silicon-Germanium technology, for use in complex multi-channel radar transceiver front-ends in the 77GHz frequency band. The main emphasis of the work is the realization of high-linearity and low-power modular receiver channels as well as the investigation of millimeter-wave integrated test concepts for the receiver front-end.

Autonomous driving of vehicles has been becoming a reality and radar is an indispensable feature of this transportation method. However, there will be interference issues due to the multiple signals transmitted from the radars on the adjacent driving vehicles operating in the same area at the same time. Consequently, radar interference mitigation techniques will be essential in such multi-vehicle environment. In order to accurately detect and localize adjacent vehicles, several radars must be carried on each vehicle. A low-cost and highly-integrated CMOS radar sensor could be the best candidate to fulfill this growing industrial need. Linear frequency-modulated continuous-wave (FMCW) radar with constant envelope waveform is suitable for low-power/ low-cost CMOS implementation. However, the ghost targets due to other radars and radio interference generate false alarms and lower the probability of detection. Some interference mitigation techniques allocating frequency sub-bands at different time for different users to avoid concurrent frequency band usage have been proposed in the past. However, the number of users must trade off with the available bandwidth so does the range resolution. This dissertation presents an interference-tolerant radar which can endure multiple signals transmitted from adjacent vehicles for autonomous driving applications. The interference immunity property has been realized by applying a specific code-division multiplexing method, involved with one-coincidence frequency hopping code, to the continuous-wave radar. A radar prototype has been implemented in 65nm CMOS for operation at 24GHz with 1GHz bandwidth (equivalently with 15cm range resolution). Measurements indicate that the prototype can support up to 22 adjacent vehicles simultaneously by using the optimized Hamming correlation property of the extended hyperbolic congruential code.

This book provides a thorough overview of cutting-edge research on electronics applications relevant to industry, the environment, and society at large. A wide spectrum of application domains are covered, from automotive to space and from health to security and special attention is devoted to the use of embedded devices and sensors for imaging, communication and control. The book is based on the 2014 APPLEPIES Conference, held in Rome, which brought together researchers and stakeholders to consider the most significant current trends in the field of applied electronics and to debate visions for the future. Areas covered by the conference included information communication technology; biotechnology and biomedical imaging; space; secure, clean and efficient energy; the environment; and smart, green and integrated transport. As electronics technology continues to develop apace, constantly meeting previously unthinkable targets, further attention needs to be directed toward the electronics applications and the development of systems that facilitate human activities. This book, written by industrial and academic professionals, will hopefully contribute in this endeavor.

There are continuous efforts focussed on improving road traffic safety worldwide. Numerous vehicle safety features have been invented and standardized over the past decades. Particularly interesting are the driver assistance systems, since these can considerably reduce the number of accidents by supporting drivers’ perception of their surroundings. Many driver assistance features rely on radar-based sensors. Nowadays the commercially available automotive front-end sensors are comprised of discrete components, thus making the radar modules highly-priced and suitable for integration only in premium class vehicles. Realization of low-cost radar fro- end circuits would enable their implementation in inexpensive economy cars, c- siderably contributing to traffic safety. Cost reduction requires high-level integration of the microwave front-end c- cuitry, specifically analog and digital circuit blocks co-located on a single chip. - cent developments of silicon-based technologies, e.g. CMOS and SiGe:C bipolar, make them suitable for realization of microwave sensors. Additionally, these te- nologies offer the necessary integration capability. However, the required output power and temperature stability, necessary for automotive radar sensor products, have not yet been achieved in standard digital CMOS technologies. On the other hand, SiGe bipolar technology offers excellent high-frequency characteristics and necessary output power for automotive applications, but has lower potential for - alization of digital blocks than CMOS.

Enabling Technologies for the Internet of Things: Wireless Circuits, Systems and Networks collects slides and notes from the lectures given in the 2017 Seasonal School Enabling Technologies for the Internet-of-Things, supported by IEEE CAS Society and by INTEL funding, and organized by Prof. Sergio Saponara, and Prof. Giuliano Manara. The book discusses new trends in Internet-of-Things (IoT) technologies, considering technological and training aspects, with special focus on electronic and electromagnetic circuits and systems. IoT involves research and design activities both in analog and in digital circuit/signal domains, including focus on sensors interfacing and conditioning, energy harvesting, low-power signal processing, wireless connectivity and networking, functional safety (FuSa). FuSa is one of the emerging key issues in IoT applications in safety critical domain like industry 4.0, autonomous and connected vehicles and e-health. Our world is becoming more and more interconnected. Currently it is estimated that two hundred billion smart objects will be part of the IoT by 2020. This new scenario will pave the way to innovative business models and will bring new experiences in everyday life. The challenge is offering products, services and comprehensive solutions for the IoT, from technology to intelligent and connected objects and devices to connectivity and data centers, enhancing smart home, smart factory, autonomous driving cars and much more, while at the same time ensuring the highest safety standards. In safety-critical contexts, where a fault could jeopardize the human life, safety becomes a key aspect.
