This book provides a clear and concise introduction to radar signal processing for nonspecialists - those who want to perform image enhancement, parameter estimation, pattern recognition, and other computer-based information extraction techniques on the radar imagery as well as cartographers, agronomists, and oceanographers. Four chapters lead the reader through the basics of radar processing, providing a thorough explanation of how to combine one dimensional radar returns into two dimensional images, a discussion of synthetic aperture radar (SAR), its optical interpretation and implementation, and an overview of other image reconstruction algorithms including tomography and ultrasound. End of chapter problems together with solutions make this volume ideal for a course on imaging systems and techniques.
