Radar: Introduction to Radar Systems -- Online Course
- Online STEM Course
- Undergraduate Students
- Graduate Students
This course is presented by Robert M. O'Donnell, a former researcher at MIT Lincoln Laboratory, and is designed to instill a basic working knowledge of radar systems.
Description of Lectures
The set of 10 lectures starts with an introductory description of basic radar concepts and terms. The radar equation needed for the basic understanding of radar is then developed, along with several examples of its use in radar system design. Radar propagation issues such as attenuation, multipath effects, and ducting are described. The concept of radar cross-section, waveform design, antennas, transmitter and receiver characteristics, and the detection of radar signals in the presence of noise are presented. Some radars are required to detect small targets in the presence of much larger radar echoes from sea or land clutter in the radar's coverage. The characteristics of this clutter are discussed with moving target indicator (MTI) and Pulse Doppler techniques for mitigating the negative effects of clutter. The course continues with lectures covering target tracking and target parameter estimation. The last lecture discusses radar transmitters and receivers.

Any person with a college degree should be comfortable understanding the material in this course. A degree in science or engineering is not required, although the material will be more readily understood if the audience has introductory college-level knowledge of the following:
- Mathematics including the topics of algebra, trigonometry, and logarithms.
- Basic physics including the topics of electricity and magnetism.
- University students or recent graduates who are contemplating employment with a corporation that develops radar systems.
- Nonengineering employees, such as accountants, lawyers, and technicians, of corporations that develop radar systems.
- Patent attorneys who deal with radar patent issues.
- Political scientists or others who deal with arms control issues.
- Engineers or scientists unfamiliar with the terms and concepts particular to radar systems engineering. These individuals should be able to go through the lectures quite quickly, learning the vocabulary of radar, so that they can promptly delve into the technical aspects of radar systems without being confused by new jargon, acronyms, and/or technical terms.
- And any curious individuals, even those who just want to know how that police officer knew they were traveling 79 miles per hour in a 65-mile-per-hour zone.
