Radar Cross Section Reduction

Course Description

In this course, you'll get an overview of electromagnetic scattering and how scattering can be controlled or modified to achieve radar cross section reduction (RCSR). You'll initially learn the basics of electromagnetic scattering and radar operation as it relates to RCS; and how RCS data is visualized, measured, and modeled. Building upon this foundation, you will learn fundamental scattering mechanisms and how to use shaping and radar absorbing materials to control and modify the scattering. Special considerations for antennas, propulsion systems, and airframes will be discussed. You’ll learn how to apply these principles to aircraft design considering operational requirements, and gain an understanding of low observable (LO) aircraft manufacturing and maintenance.

This course has an accompanying/add-on Radar Cross Section Reduction Lab course that is highly recommended. The lab takes place the day after the RCSR course. In the lab course, you’ll gain hands on experience with tools and techniques for RCSR. In the morning session you’ll use several computational electromagnetics tools for RCSR, learn about materials characterization, and tour a compact range. In the afternoon session, you’ll work in teams to treat a test object, competing to minimize its RCS. In this session, you’ll gain hands-on experience with materials and treatment characterization, and apply materials and treatments to a test object.

You’ll have the option to add the lab course when registering for the RCSR course.
