Radars are used in a large variety of applications and their main architecture main change somewhat from case to case. However, for intelligence gathering purpose, the main feature that a technical observer can distinguish is its antennas. Moreover, the technical status of the radar may also be inferred and any technological breakthrough may be investigated. This course will deal with two main subjects: The first one is to describe the several kinds of radar and their main applications. The second one is how these radars must spread into space the energy provided by their transmitters. The analysis of such feature is crucial to pinpoint the possible use of the radar.
Modern radars face the challenge of low Radar Cross Section (RCS) targets. These targets are designed with the intention to reflect the least possible energy back in the direction of the incident radar signals. These studies are conducted since the radar early days at II World War and today there are plenty of examples of aircrafts and ships of very low RCS. This Short Course intents to present radar signal propagation and to describe the Radar Cross Section of specific targets. It will show how the use of special materials and proper shaping of the target superstructure can reduce this parameter. It will also be discussed how radars can overcome such measures and be able to detect the so-called stealth platforms. The course will first describe the basics of radar signal propagation and how the RCS will limit the target detection. After the main techniques used to reduce the platform’s RCS will be described. In sequence, several examples of stealth aircrafts, ships, missiles and land vehicles will be shown and commented. Finally, some techniques used by radar designers to provide them with low RCS detection capability are discussed. This course will also be useful to introduce graduate engineers and students to the radar science which is a field closely related to telecommunications engineering.
After the courses of Dr Antônio D. Macedo-Filho, a form will be distributed to those, under 30, interested to join the Association of Old Crow (http://www.crows.org/). In a promotion for the IMOC 2017 attendees, AOC will provide 3 free annuities. Non-members will be offered a $ 25 annuity (something close to $ 100 with all fees). Members will receive a monthly journal, JED (Journal of Electronic Defense), and will have access to several Web courses (including archives of those already held at previous events). The form will be also available at IMOC registration desk as the promotion is extended to SBMO members.
In an era where the demand for IP traffic from users and enterprises is constantly increasing, coherent optical communications are widely established as the most effective solution to ensure high capacity per bandwidth over distances that range from a few kilometers to thousands of kilometers. Today, coherent optical technologies represent the core of metro and long-haul transmission systems, enabling transmission of a tremendous amount of data with the highest spectral efficiency. More recently, coherent optics also gained wide interest for shorter reach applications, such as data center interconnect, due to its technological maturity and increasing cost effectiveness compared to direct detection systems. This short course will give an overview on digital coherent optical technologies, both from a system and signal processing point of view. In the first part of the course, the building blocks of a coherent optical system will be reviewed, along with the main transmission scenarios. The second part will focus on digital signal processing techniques for signal generation and detection, highlighting its benefits and pointing out the main challenges to be overcome for each of the proposed transmission scenarios.
Beyond telecommunications optical fibers can also transport optical energy to powering electric or electronic devices remotely. This technique is called power over fiber (PoF). Besides the advantages of optical fiber (immunity to electromagnetic interferences and electrical isolation) the employment of a PoF scheme can eliminate the energy supply by metallic cable and batteries located at remote sites, improving the reliability and the security of the system. PoF is very interesting technique to be applied in Smart Grid. Smart Grid is seen by experts as the output to a new technological level seeks to incorporate extensively technologies for sensing, monitoring, information technology and telecommunications for the best performance electrical network. On the other hand in passive optical networks (PON) PoF can make PON extenders virtually passives. This short course describes the PoF principle, its main elements, technologies and the applications focusing in access networks and in smart grid developed by the author. Objectives: We will present in this course not only a comprehensive review of PoF since the 70's when it was published the first paper for telecommunication application, but a complete explanation about how it works and how it has been applied in real field applications.
This short course will give the student the overall understanding of what signal integrity is, the main technical challenges, and the common solutions. It will address how the microwave/electromagnetic community can contribute in the signal integrity development. The industry trends, state-of-the art solutions and advanced techniques will also be discussed. At the end, the student should be able to identify critical technical challenges in the design phase of high-speed circuits. He should also be able to recognize the industry leaders, what the trends are, and some of the new products and technologies that are coming to the market.
