Paseo Colón 850 (In-Person Event / Evento Presencial) OPENING Welcome Message Prof. Alejandro Martínez (Dean FIUBA) Event Introduction Prof. Gustavo Fano – Prof. Ramón López La Valle – IEEE Student Branch of FIUBA TECHNICAL PRESENTATIONS From Engineering Electromagnetics to Electromagnetic Engineering: Teaching/Training Next Generations Prof. Levent Sevgi (Istanbul Technical University, IEEE AP-S DLC Chair, Founding Chair EMC TÜRKİYE) The role of Electromagnetic (EM) fields in our lives has been increasing. Communication, remote sensing, integrated command/control/surveillance systems, intelligent transportation systems, medicine, environment, education, marketing, and defense are only a few areas where EM fields have critical importance. We have witnessed the transformation from Engineering Electromagnetics to Electromagnetic Engineering for the last few decades after being surrounded by EM waves everywhere. Among many others, EM engineering deals with broad range of problems from antenna design to EM scattering, indoor–outdoor radiowave propagation to wireless communication, radar systems to integrated surveillance, subsurface imaging to novel materials, EM compatibility to nano-systems, electroacoustic devices to electro-optical systems, etc. The range of the devices we use in our daily life has extended from DC up to Terahertz frequencies. We have had both large-scale (kilometers-wide) and small-scale (nanometers) EM systems. A large portion of these systems are broadband and digital and must operate in close proximity that results in severe EM interference problems. Engineers must take EM issues into account from the earliest possible design stages. This necessitates establishing an intelligent balance between strong mathematical background (theory), engineering experience (practice), and modeling and numerical computations (simulation). This Distinguished/keynote lecture aims at a broad-brush look at current complex EM problems as well as certain teaching / training challenges that confront wave-oriented EM engineering in the 21st century, in a complex computer and technology-driven world with rapidly shifting societal and technical priorities. Maritime Multi-Sensor Integrated Surveillance Systems Based on Surface Wave High Frequency Radars Prof. Levent Sevgi (Istanbul Technical University, IEEE AP-S DLC Chair) Countries with substantial coastal regions require greatly enhanced systems to monitor activity occurring within their Exclusive Economic Zones (EEZ). According to the United Nations Convention on the Law of the Sea (UNCLOS) of 992, participating countries have extensive exploitation rights within the EEZ, which extends up to 200 nautical miles (nm) from shore. Activity will include isolated or grouped, moving and/or anchored surface targets and low-flying aircraft. The targets may be military/commercial, friend/foe, small/large. Besides the economic benefits, a participating country carries responsibilities such as prevention of smuggling, terrorism and piracy; the effective management and protection of offshore fisheries; search and rescue, vessel traffic services, pollutant control as well as meteorological and oceanographic data collection. Traditional land-based microwave radars are limited to line-of-sight, which means a maximum range of 50-60km even with an elevated radar platform. The EEZ can be covered by microwave radar in a patrol aircraft, but requires three to five aircraft (well above 20,000ft) with many hours on station. Satellites have neither the spatial nor the temporal resolution to provide this surveillance in real-time. Sky wave high frequency (HF) radars can be used for this purpose, but they need large installations, are expensive and detection of surface targets is still limited. Optimum sensor for EEZ surveillance seems to be the Surface Wave HF radar. This DL/Keynote talk is about modeling and simulation strategies and challenges in integrated maritime surveillance systems based on High Frequency Surface Wave Radars (HFSWR). Topics to be covered include fundamental radar concepts, HFSWR signal characteristics (signal, noise, clutter, interference, etc.), Surface wave propagation modeling and mixed-path effects, Transmit/Receive Antenna systems and beam forming/steering, Target reflectivity and RCS prediction/reduction, and Stochastic modeling.
