ECE 492/592: Intro to Radar Systems

Description:

Introduction to basic principles of radar and key radar sub-systems: transmitter and receiver architectures; sub-components, e.g. filters, amplifiers, mixers, and oscillators; sources of degradation, such as noise and non-linearity; radar range equation, phenomenology (target reflectivity models, clutter, stealth and scattering), radar measurements of range and velocity, basic radar waveforms, pulse compression, coherency. Technical writing proficiency and communication skills will be honed in this course through oral and written student presentations/assignments. A “learn through experimentation” philosophy is espoused in the class via experiments/projects conducted using software-defined CW/FMCW radars and cyber-physical human systems (CPHS).

Recommended Pre-Requisites:

ECE 211/ECE 331 Circuit Analysis and ECE 301 Linear Systems (or equivalents)
