Learn the newest processing techniques for focusing radar images with this important new book. It helps you master the SAR/ISAR fundamentals that are critical to understanding motion compensation and advanced SAR/ISAR imaging techniques, and gives you the background you need to tackle problems such as estimating motion parameters by phase analysis, compensating the phase of a wideband signal, and processing a wideband signal into a radar image. In 14 chapters, with over 100 illustrations and nearly 300 equations, the authors introduce, develop and test methods for estimating the motion parameters of a target, and present an integrated approach for generating focused radar images of multiple moving targets illuminated by a radar beam. Focusing on motion compensation of radar images, the book examines the development of filtering and reconstruction processes that allow for individual target motion compensation, discusses the implementation of this approach using the Gabor wavelet transform, and incorporates image enhancement techniques for the generation and identification of simulated and real aircraft images that cannot be obtained using conventional radar processors.
