内容説明
This text explores processing techniques for focusing radar images. It offers to help the user master the SAR/ISAR fundamentals that are critical to understanding motion compensation and advanced SAR/ISAR imaging techniques, and also presents the background you need to tackle problems such as estimating motion parameters by phase analysis, compensating the phase of a wide-band signal, and processing a wideband signal into a radar image. The accompanying diskette, written in MATLAB, allows the user to simulate implementation of the techniques presented in the book, and to make modifications to the simulations to facilitate the understanding of these techniques. The system requirements for running the disk are: IBM-compatible PC with 2 MB disk space.
