This introductory course provides a systems view of airborne radar. Basic formulas are presented along with an explanation of their significance to the design process. Radar performance calculation is described as a means of evaluating key trade-offs. Practical examples are presented with simulations that help to justify the reasons for design choices.
The course briefly touches on most of the important issues in the broad subject area of airborne radar, including:
- Hardware units (antenna, receiver, etc.)
- Waveform design (choice of radio frequency and pulse repetition frequency)
- Environmental effects (radar clutter, atmospheric effects)
- Radar applications (ground mapping, target tracking, weapon delivery)
- Simulation of radar performance
The course is intended for:
- Managers and technologists seeking a broad overview of airborne radar
- Entry-level engineers who have little or no background in radar
- Subsystem designers who are looking for a system-level view of radar
- An up-to-date view of the key issues involved with airborne radar design
- System-level insight without lengthy mathematical derivations
- Discussion of recent developments, such as low observable and low probability of intercept design
The text, Introduction to Airborne Radar, George Stimson (SciTech Publishing, 1998), and lecture notes are distributed on the first day of the course. These notes are for participants only and are not for sale.
