Subject fundamentals
The course is taught in English.

Radars are more and more pervading systems applied not only in highly technological environments (air traffic control, battle fields and the ˇinevitableˇ¨ electronic counter-measures systems, ...) but in everyday life (car parking systems, collision avoidance systems, body scanners in airports, alarm devices, ...) and in the environmental monitoring (rain radar, all weather land and ocean imaging, ...). Radars are ˇactiveˇ¨ remote sensors, however a very important contribution to environmental monitoring is given by completely ˇpassiveˇ¨ remote sensors operating in different spectral regions (e.g.: infrared for temperature measurements, microwave for cloud, clear atmosphere and land monitoring, ˇK).
Both in the active systems like radars and in the passive systems, the signal analysis was initially performed through analog electronics, then through dedicated digital processors. Presently numerical processing and data analysis is the usual tool adopted to efficiently extract information from the ˇsignaturesˇ¨ that radar targets and natural or man-made objects are putting on the electromagnetic waves, according to the so-called ˇsoftware radioˇ¨ approach.
This course introduces a set of technical applications representing a synthesis of electromagnetism, electronics, telecommunications and informatics.
Expected learning outcomes
The students will acquire capability of evaluating order-of-magnitude parameters of radar systems and remote sensing systems, in the applications related to detection and characterization of man-made objects and natural environment. In particular, they should be able to define technical specification of systems devoted to measuring distance, velocity, shapes of object moving in space, in the atmosphere and on surfaces. Students will be faced with problems related to interference and electromagnetic compatibility. Similarly they will gain the ability to evaluate physical properties of our environments (the atmosphere, sea surfaces, land, ˇK).
Prerequisites / Assumed knowledge
Basic knowledge from the mandatory teachings in physics, electromagnetism and informatics. In particular knowledge on the following fields are required: Maxwell equations, plane waves theory, free space propagation, role of refraction index, plane wave refraction and reflection from planar surfaces, black body concepts, signal theory basics. Knoweledge of Matlab environment is also required.
Contents
Introduction related to the nature and properties of electromagnetic waves, antennas and EM propagation in atmosphere, evaluation of emitted field levels also in relation with international regulations and recommendations for exposure to EM fields ('î14 hours); details about Radar concepts ('î8 hours); Radar signal processing techniques ('î4 hours); Radar systems for detection and remote sensing purposes (surveillance and tracking Radar, Synthetic Aperture Radar, Meteorological Radar, Ground Penetrating Radar, 'î20 hours); details about interferences reduction, anti jamming procedures and electromagnetic compatibility problems ('î4 hours). As far as the passive Remote Sensing field is concerned, the lecturers will describe techniques and systems as a function of frequency bands for atmospheric sensing ('î10 hours) and surface sensing ('î6 hours).
Delivery modes
Several practical activities covering basic radar concepts and active/passive remote sensing concepts will be proposed ('î20 hours). Such activities will be carried out in our LAIBs mainly using MatLab and Geographical Information Systems. Small working groups will be formed; the production of brief reports containing results obtained by the practicing students will be recommended although their writing will not be mandatory. Also classroom exercises will be proposed, integrating theoretical lessons with numerical applications. External visits to our laboratories and to Radar installations will be organized.
Texts, readings, handouts and other learning resources
For each lesson, practical activity and exercises, power point or pdf presentations will be made available through the personal page of the ˇ§Portale della didatticaˇ¨. This is the reference material for the lecturers. Reference text books are:

Skolnik M. I., Radar Handbook, McGraw-Hill, 2008
Elachi C., Introduction to the Physics and techniques of Remote Sensing, Wiley, 1987

Suggested readings can be found in:

Richards M. A., Fundamentals of Radar Signal Processing, McGraw-Hill, 2005
Janssen M. A., Atmospheric Remote Sensing by Microwave Radiometry, Wiley, 1993
Kerr D. E., Propagation of short radio waves, Peregrinus, 1987
Assessment and grading criteria
In the formal exam session just before the end of the lecturers, the final written exam will be a multiple choice test on PC. The oral exam is possible for those who want to improve the score reached in the written part, only it they passed a given threshold. During all the other exam sessions, the exam will be an oral exam. In this case the teacher may ask to the student to solve some simple exercises.
Reports prepared by the students during laboratories (which are not mandatory) may be used in the final evaluation.
