Wideband Radar focuses on system theories and signal processing techniques for wideband radar systems. Author Professor Teng Long and his fellows present a comprehensive introduction to the fundamental theory, latest technology developments in signal processing and recent progresses in civil applications of wideband radar. Each chapter begins with an introduction describing what a reader will find in that chapter. The book is addressed to all scientists, whether at universities or in industry, who wish to keep abreast of the important advances in wideband radar. We look forward to further excitement ahead and new developments in wideband radar, and we hope to share them with you, our esteemed readers.
