This book presents a comprehensive exploration of radar science, examining the principles, technologies, and operational frameworks that enable the detection and analysis of objects at a distance. It considers how electromagnetic waves are utilised to determine position, movement, and characteristics of targets, highlighting the scientific foundations that support accurate measurement and signal interpretation. The narrative reflects on the progression of radar systems from early developments to advanced technologies capable of operating across complex environments. It also explores how modern radar integrates sophisticated techniques to enhance resolution, range, and reliability, enabling its application in both civil and strategic contexts. Attention is given to the role of signal behaviour, system design, and technological refinement in shaping effective radar performance.

The book also highlights the practical significance of radar technology in areas such as navigation, surveillance, and environmental monitoring. It offers insight into how radar systems continue to evolve in response to technological demands, making it valuable for students, engineers, and professionals interested in sensing and detection technologies.
