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 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.

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. The students are expected to assess the learning outcomes through the solution of exercises on the course subjects. The exercises are evaluated both in terms of the solution method and in terms of calculated results. 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. The questions are directed to verify the theoretical and practical understing of the course subjects.

Gli studenti e le studentesse con disabilitą 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'Unitą Special Needs, al fine di permettere al/la docente la declinazione pił idonea in riferimento alla specifica tipologia di esame.

The questions are directed to verify the theoretical and practical understing of the course subjects.
The exam with remote connection will be oral using the zoom platform. The exam will be divided in three parts:
1) two or three very simple questions to be answered in short time;
2) one question on the principle of operation and usage of a method or a device;
3) the solution of a simple exercise that is similar to a part of one of the problems proposed during the course.

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.

The oral exam will be divided in three parts:
1) two or three very simple questions; examples are: the range given the two way time delay, the doppler frequency shift given the target velocity and wavelength, the range resolution given the bandwidth, MTI blind speed given the PRF and wavelength, ...
2) one question on the principle of operation and usage of a method or a device; example are: describe a digitally modulated radar waveform, how do you realize a low pass filter, what is a circulator, describe a range-doppler radar, ...
3) the solution of a simple exercise that is similar to a part of one of the problems included in the home assignments.
Maximum oral test score will be 27/30; home assignments score will allow to reach 30 cum laude. Extra questions can be requested if not satisfied with your home assignments score.
