The word RADAR is an abbreviation for RAdio Detection And Ranging. In general, radar systems use modulated waveforms and directive antennas to transmit electromagnetic energy into a specific volume in space to search for targets or to remote sensing. Targets reflect portions of this energy (echoes) back to the radar. This course is a comprehensive and detailed description and presentation about radar systems analysis and design that can provide the students with hands-on-like experience. The course concentrates on radar fundamentals, principles, and mathematical derivations. It also provides the student with a comprehensive set of tools that can be used for radar analysis and/or radar system design. This course serves as a valuable resource to students in analyzing and understanding the many issues associated with radar systems analysis and design and remote sensing. The course is taught in English.

The most common concepts used in radar systems, such as range, range resolution, Doppler frequency, and coherency are described. The radar range equation, Radar Cross Section (RCS) and radar losses are addressed. RCS formulas for many simple objects as well as complex object RCS are presented. Continuous Wave (CW) radars and pulsed radars are discussed. Resolving range and Doppler ambiguities is also discussed in detail. A review of radar waveforms, including CW, pulsed, Linear Frequency Modulation (LFM), High Range Resolution (HRR) waveforms and stepped frequency waveforms are analyzed. The concept of the matched filter and the radar ambiguity function are introduced. Pulse compression and binary phase codes and frequency codes are discussed. The phenomenology of radar wave propagation including topics like multipath, refraction, diffraction, divergence, and atmospheric attenuation is addressed. The concepts of clutter and Moving Target Indicator (MTI) are also addressed. Synthetic Aperture Radar (SAR) and remote sensing are the subjects of the last part of the course. According to the course evolution we present an overview of radar signal processing. Moreover, the course illustrates the principles of operation, and provides the design criteria for the main microwave passive components used in radar systems. Finally, the course provides an introduction to electromagnetic compatibility, with particular emphasis on signal integrity and radiated interferences. Software simulations and realistic application examples are presented and discussed all along the course.

Practical and realistic exercises (exam-like) related to the concepts described during classes are proposed weekly. Such activities are carried out in classroom or LAIB also using MATLAB. Laboratory experiences using real radar system are organized during the course.

ModalitÓ di esame: Prova scritta (in aula); Prova orale facoltativa;
Exam: Written test; Optional oral exam;
... The exam consists of a written test including 3 exercises (similar to those proposed during the course) to be solved in 2 hours. During the exam it is strictly avoided to have developed exercises, notes or textbooks. To improve the obtained score from the written test it is possible to hold an oral test (2 questions) that can increase or decrease the written test score.
Gli studenti e le studentesse con disabilitÓ o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'UnitÓ Special Needs, al fine di permettere al/la docente la declinazione pi¨ idonea in riferimento alla specifica tipologia di esame.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
