Description

The ability to detect and locate targets by day or night, over wide areas, regardless of weather conditions has long made radar a key sensor in many military and civil applications. However, the ability to automatically and reliably distinguish different targets represents a difficult challenge, although steady progress has been made over the past couple of decades.

Radar Automatic Target Recognition (ATR) and Non-Cooperative Target Recognition (NCTR) captures material presented by leading international experts at the NATO SET-172 lecture series which provided an overview of the state-of-the-art and continuing challenges of radar target recognition, both automatic (ground) and non-cooperative (air). This book explores both the fundamentals of classification techniques applied to data from a variety of radar modes and selected advanced techniques at the forefront of research.

Topics include:

• The problem as applied to the ground, air and maritime domains
• Impact of image quality on the overall target recognition performance
• Performance of different approaches to the classifier algorithm
• Improvement in performance to be gained when a target can be viewed from more than one perspective
• Ways in which natural systems perform target recognition
• Impact of compressive sensing
• Advances in change detection, including coherent change detection
• Challenges and directions for future research
