Learning Objectives
This will be a 4th year/Post Graduate course for those interested in the areas of radars, microwave engineering, and remote sensing. The course will introduce the basics of radar and radiometer operations and will cover the basic design principles of various radars as well as radiometer systems. There will be a quick introduction to antenna theory so that those without this background can take this course. Basic EM theory (not a comprehensive knowledge) and basic antenna concepts are preferred.
Learning Outcomes
- Explain concepts of a radar and a radiometer.
- Calculate the various radar and radiometer parameters.
- Apply the concepts in target detection and atmospheric conditions analysis.
Course Content
- Review of antennas, directional couplers, power dividers.
- Radar Basics: transmitter and receiver details, radar equation, range prediction; minimum detectable signal (sensitivity); receiver noise; radar cross section of targets; concept for matched filter.
- Pulsed Doppler radars, radar hardware and electronics, pulse repetition frequency; limitations of moving target indication (MTI) radar, non-coherent MTI.
- Radar signal acquisition system, analog-to-digital conversion, time-domain processing, Fourier analysis: continuous-time and discrete-time.
- Radars for observing distributed targets/remote sensing: Rain detection and rain rate determination.
- Microwave Radiometry; fundamental aspects of microwave radiometric measurements, receivers and radiometer systems design, effects of noise figure on system performance, theory of radiative transfer equation.
