Description
This three-day course introduces the student to the fundamentals of radar systems engineering. The course begins by describing 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 a explanation of radar detection and tracking of targets in noise and clutter. The course is valuable to engineers and scientists 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. Students will also receive Matlab scripts that they can use to perform radar system performance assessments.
What You Will Learn:
- 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.
Course Outline:
- 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), Swerling model for fluctuating targets, volume and surface clutter, and ground and ocean clutter models.
- Propagation of RF Signals. Free space propagation, atmospheric attenuation, ducting, and significance of RF transmit frequency.
- Radar Transmitter/Antenna/Receiver.Antenna concepts, phased array antennas, radar signal generation, RF signal heterodyning (upconversion and downconversion), signal amplification, RF receiver components, dynamic range, and system (cascade) noise figure.
- Radar Detection. Probability Density Functions (PDFs), Target and Noise PDFs, Probability of Detection, False Alarm Rate (FAR), constant FAR (CFAR) threshold, receiver operating characteristic (ROC) curves.
- Radar Tracking. Range and angle measurement errors, tracking, Alpha-Beta trackers, Kalman Filters, and track formation and gating.
