Radar Systems Analysis & Design Using MATLAB
This course provides a comprehensive description of radar systems analyses and design. A design case study is introduced and as the material coverage progresses throughout the course, and new theory is presented, requirements for this design case study are changed and / or updated, and the design level of complexity is also increased. This design process is supported with a comprehensive set of MATLAB-7 code developed for this purpose. By the end, a comprehensive design case study is accomplished. This will serve as a valuable tool to radar engineers in helping them understand radar systems design process. Each student will receive the instructor’s textbook MATLAB Simulations for Radar Systems Design as well as course notes.
What you will learn:
- How to select different radar parameters to meet specific design requirements.
- Perform detailed trade-off analysis in the context of radar sizing, modes of operations, frequency selection, waveforms and signal processing.
- Establish and develop loss and error budgets associated with the design.
- Generate an indepth understanding of radar operations and design philosophy.
- Several mini design case studies pertinent to different radar topics will enhance understanding of radar design in the context of the material presented.
