EE473 Principles of Radar and Electronic Warfare
Catalog Data & Credits (Recitation-Lab-Total)
EE473 Principles of Radar and Electronic Warfare (3-0-3): The course offers radar fundamentals, intermediate radar topics, special radar topics, and an overview of electronic warfare (EW). Fundamentals include the basics of range and Doppler estimation using pulsed and CW signals, radar detection theory, radar components, range and Doppler estimation, PRF and radar ambiguities. Intermediate topics include propagation issues, clutter processing, MTI and pulse Doppler, and tracking. Special topics include synthetic aperture radar (SAR) imaging, over-the-horizon (OTH) radar, and bistatic radar. The EW part of the course looks at each of the three EW principles: EA, EP, and ES - in turn, examining technologies and techniques.
Pre-requisites
EE372 - Engineering Electromagnetics and EE354 - Modern Comm Systems With Cyber Applications
Course Objectives
- Demonstrate an understanding of the basics of radar pulse trains, including Pulse Repetition Interval (PRI) and Pulse Repetition
- Frequency (PRF), range resolution, unambiguous range, minimum and maximum range.
- Develop an understanding of the coherency in modern radar systems, and its importance for radar modes such as Pulse Doppler and MTI, in particular for clutter mitigation.
- Learn the roles of the key components of a modern radar system: exciter, transmitter, receiver, and antenna. Know the chief design tradeoffs for transmitters; know how to determine noise temperature for a receive chain with both passive and active components; know key concepts in antenna directivity and beam shape; know the importance of exciters in coherency.
- Be familiar with the basic concepts of Detection Theory, including the setting of detection threshold on noise, and calculation of probability of detection and probability of false alarm for standard statistical distributions in single-pulse and the more-used multiple-pulse detection approaches.
- Be familiar with special radar topics such as imaging, over-the-horizon ``radar’’ (I am using quotes here because OTH does not tend to use microwave frequencies but in all other respects it functions like radar), and bistatic/multi-static radar.
- Know the three main areas of Electronic Warfare and specific approaches within those areas. Be aware of LPI and basic approaches in LPI radar.
