Survey of Electromagnetic Sensors and Detection

Course #PC3200

Est.imated Completion Time: 3 months

Overview

A survey of the physics of active and passive electromagnetic sensor technologies and detection methods used in surface, air, space, and undersea warfare. Topics include basic radiometry; detector figures of merit and noise characteristics; types of visible and infrared detectors; radar basics, including modes of detection, range resolution, target cross-sections, and the range equation; and magnetometry basics and detectors. Applications of these topics to combat systems will be discussed, including optical and thermal imaging, heat signatures, magnetic signatures, night vision, target/background discrimination, and missile seekers.
