- • How radars measure target range, bearing and velocity. • How the radar range equation is used to estimate radar system performance including received power, target SNR and maximum detection range. • System design and external factors driving radar system performance including transmitter power, antenna gain, pulse duration, system bandwidth, target RCS, and RF propagation.
This 5-day course introduces the fundamentals of radar and Primary radar systems engineering. The course begins by describing the background, historical overview and basic principles of operation. Students will learn also how radar sensors perform critical measurements and the limitation of those measurements. The radar range equation in its many forms is derived, and examples of its applications to different situations are demonstrated. The generation and reception of radar signals is explained through a holistic rather than piecemeal discussion of the radar transmitter, antenna, receiver and signal processing. The course wraps up with an explanation of radar detection and tracking of targets in noise and clutter. Types of radar displays, rotary joint and waveguides in use are well explained. The course is valuable to engineers, technicians and students who are entering the field or as a review for employees who want a system level overview. A comprehensive set of notes and references will be provided to all attendees.

After completing the course, participants will have a good understanding of the “big picture” of the radar system and its management. In addition, participants will have information and skills that will assist them in practical radar deployment plans, in particular: Radar Measurements. Target ranging, target bearing, target size estimation, radar range resolution, range rate, Doppler velocity, and radar line-of-sight horizon. Radar Range Equation. Description of factors affecting radar detection performance; system design choices such transmit power, antenna, signal frequency, and system bandwidth; external factors including target reflectivity, clutter, atmospheric attenuation and RF signal propagation; use of radar range equation for estimating receive power, target signal-to-noise ratio (SNR), and maximum detection range. Target and Clutter Reflectivity. Target radar cross section (RCS), volume and surface clutter, and ground and ocean clutter. Propagation of RF Signals. Free space propagation, atmospheric attenuation, ducting, and significance of RF transmit frequency. Radar Transmitter/Antenna/Receiver. Antenna concepts, radar signal generation, RF signal heterodyning, signal amplification, RF receiver components, dynamic range, and system noise figure. Radar displays and Waveguides used in radar systems. Probability of detection and false alarms are well explained. Anti-Clutter devices: CKTs for swept gain receiver, fast time constant and logarithmic amplifier.
