Overview

Modeling and Simulation of Phased-Array Antennas

Course Description

Phased array antennas are key, yet complicated sub-systems in modern radar, electronic warfare, and communications systems. Computer simulation of phased arrays is simple to a first order, using sinc functions or basic Fourier transforms. Simple models leave out important details which are the result of both electromagnetics physics and hardware component and architecture selections. This course will provide the detail needed for the modeler to understand what features are important to include and how to affect them in the simulation. Much of the course relies on Matlab model components. Software will be provided along with computers for student use during the course.
