Cognitive theory applied to radar system

Abstract

Cognition, a basic concept in psychology, is the set of a human's inner mental activities and processes related to knowledge. Actually it is possible to introduce cognition into engineering systems to construct intelligent systems with human cognitive functions. Cognitive radar is such a successful case that improves the working performance in complex environment. The article starts with the concept of cognition and cognitive radar, subsequently followed by the basic elements including intelligent information processing, information feedback. The fundamentals about how cognition increases the perceptual ability of radar are discussed in detail.
