|Outline and Purpose of the Course||In this course, students learn about various types of electromagnetic field analysis techniques and antenna pattern synthesis theory used in characteristic analysis and design of antenna. Then, an overview of radio application technologies (radio-wave propagation, different types of radar, etc.) is presented, as well as a look at the current situation regarding these technologies.|
|Course Goals||Based on a knowledge of radio engineering, students will gain a higher level of understanding of electromagnetic-wave concepts and of specific technologies in which electromagnetic waves are used.|
|Schedule and Contents||
Pattern synthesis for array antenna (2-3 classes)
Students learn the fundamentals of optimal pattern synthesis theory used to improve array antenna gain and to suppress sidelobes. Taken up especially are Dolph-Thebysheff and Taylor methods. Students also learn about adaptive array technology.
Fundamentals of electromagnetic field analysis (3-4 classes)
Explained are the principles and characteristics of various methods used to determine electromagnetic fields radiating from antennas and dynamic impedance, including the finite element method (FEM), electromotive force method, method of moments, physical optics method, finite-difference time-domain (FDTD) method, etc.
Radio wave propagation (2-3 classes)
Explained are fading in wireless communications, propagation in outer space communications, remote sensing applications, etc.
Radar technology (2-3 classes)
Explanation is made of principles of measuring distance and speed using radar, and of element technologies including pulse compression method, etc. Discussion also covers the principles and signal processing methods of example applications of radar technologies, including meteorological radar, atmospheric radar, and synthetic aperture radar.
Radio navigation (1-2 classes)
Explanation is made of the principles of technologies for measuring the positions/locations of ships and aircraft, etc., by using radio waves. Discussion also covers an overview and applications of radio navigation methods, as represented by the global positioning system (GPS).
Confirmation of extent of student learning (1 class)
Confirmation (evaluation) is made of the extent that students have learned the contents of this course.
|Evaluation Methods and Policy||
Scores on regular tests (80%) Student performance in classes (20%)
The following grades are given in accordance with the goal-achievement levels of each individual student:
A+: Course goals have been accomplished at an extremely high level, from all perspectives.
A: Course goals have been accomplished at a high level, from all perspectives.
B: Course goals have been accomplished, from all perspectives.
C: Confirmation can be made, from a majority of perspectives, of effects of student learning, and course goals have been accomplished to a certain extent.
D: While course goals have been accomplished to a certain extent, further effort by the student is desirable.
F: No confirmation can be made of effects of student learning, and it is difficult to say that a student has accomplished the goals of this class.
|Course Requirements||Students are required to be taking or to have taken a course in radio engineering.|
|Study outside of Class (preparation and review)||Students should prepare and review the contents as instructed during each class period.|
