Radar Principles and Applications
In This Section
This course covers the fundamentals of radar systems. The basic radar techniques are discussed including moving target indication, pulse Doppler, measurement of range and velocity, signal-to-noise ratio and clutter cancellation. Various types of radar system are covered: synthetic aperture, weather radar, bistatic, search, tracking, and more. Radar system hardware is also discussed.
- The objective is to provide all students with an understanding of fundamental radar principles and techniques, and how they are used in a variety of radar applications.
- Concepts are introduced with both mathematical explanations and graphical illustrations. Therefore students without a strong math background can grasp the physical principles.
- The course content includes a review of the required background material, the introduction of basic radar theory and techniques, and discussion of several radar systems and applications.
- The course is self-contained in that all of the background material is included.
- There are an extensive number of worked examples.
- Some Matlab software is also provided and Matlab examples are included in the lectures.
Who Should Attend:
The course will benefit engineers both young and old who need a basic understanding of gas turbine engine systems & components and the associated design process. The course is designed for engineers with some familiarity of basic aerodynamics, gas dynamics & thermodynamics. Some knowledge of engine cycles will also be useful.

Since course notes will not be distributed onsite, AIAA and your course instructor are highly recommending that you bring your computer with the course notes already downloaded to the course.
Once you have registered for the course, these course notes are available about two weeks prior to the course event, and are available to you in perpetuity.
