Description: 这本书提供了充分的代表性逆合成孔径雷达（ISAR）成像，这是一种流行和重要的雷达信号处理工具。本书涵盖了所有可能的ISAR成像方面。这本书提供了一个介绍了专家组的逆问题和合成孔径雷达（SAR）提出的问题之前，信号处理技术和雷达基本相当。如高分辨率SAR的重要概念，脉冲压缩和图像形成连同相关的MATLAB代码。 ISAR成像的基本原理后，这本书提供了相关的MATLAB函数和代码成像ISAR成像的详细程序。 ISAR成像，多个成像技巧和微调，如零填充和窗口程序，以提高图像的质量也被提出。最后，逆合成孔径雷达图像中的各种实际应用，如成像天线平台散射的，是在单独的一章。所有这些算法，MATLAB代码和数字都包括在内。最后一章考虑了在ISAR成像的先进理念和发展趋势。-This book provides a full representation of Inverse Synthetic Aperture Radar (ISAR) imagery, which is a popular and important radar signal processing tool. The book covers all possible aspects of ISAR imaging. The book offers a fair amount of signal processing techniques and radar basics before introducing the inverse problem of ISAR and the forward problem of Synthetic Aperture Radar (SAR). Important concepts of SAR such as resolution, pulse compression and image formation are given together with associated MATLAB codes. After providing the fundamentals for ISAR imaging, the book gives the detailed imaging procedures for ISAR imaging with associated MATLAB functions and codes. To enhance the image quality in ISAR imaging, several imaging tricks and fine-tuning procedures such as zero-padding and windowing are also presented. Finally, various real applications of ISAR imagery, like imaging the antenna-platform scattering, are given in a separate chapter. For all these algorithms, MATLA

Description: Phase-Gradient autofocus (PGA) technique is
robust over a wide range of imagery and phase error
functions but the convergence usually requires 4-6
iterations. In this paper, we propose to speed up the
estimation convergence by selectively increasing the pool of
quality synchronisation sources and not to be limited by the
range pixels of the SAR map. This is highly probable since
each range bin contains more than 1 prominent scatterers
across the integration aperture. It is also highly probable
that the least brightest selected scatterer in a range gate may
turn out to be of higher energy as compared to the
maximum brightest scatterer of another gate. With
appropriate target filtering to final select the quality
scatterers out of the large pool and higher-order phase error
measurement tool, the new algorithm achieves near
convergence quality without iteration. We named this
solution the Quality PGA algorithm (QPGA).
