PHYS4421Radars and Antennae5 ch (5C/L)
Role within programme and connections to other courses. Introduces basic radar concepts and antenna theory. Content. Basic antenna theory, types of antennas for space applications, estimation of the antenna gain and radiation patterns, antenna selection and design, the radar equation and examples of radar. Radar cross-section, waveform design, antennas, and transmitter and receiver characteristics are discussed. The effect of noise in the detection of the signal and propagation effects such as attenuation, multi-path effects, and ducting are described. Ends by connecting different types of radars to different types of antennas through impedance matching and maximum power transfer concepts. 

Prerequisites: PHYS 4322, MATH 3503, ECE 3511.
