Journal ArticleDOI
Minimum-entropy phase adjustment for ISAR
TL;DR: In this paper, a new technique is developed for phase adjustment in ISAR imaging, where the adjustment phase is found by iteratively solving an equation, which is derived by minimising the entropy of the image.
Journal ArticleDOI
Superpixel-Based Classification With an Adaptive Number of Classes for Polarimetric SAR Images
TL;DR: A novel superpixel-based classification framework with an adaptive number of classes for PolSAR images that is capable of improving the classification accuracy, making the results more understandable and easier for further analyses, and providing robust performance under various numbers of classes.
Journal ArticleDOI
SAR Minimum-Entropy Autofocus Using an Adaptive-Order Polynomial Model
Junfeng Wang,Xingzhao Liu +1 more
TL;DR: A new algorithm is presented for autofocus in synthetic aperture radar imaging that applies more widely than the minimum-entropy algorithms with a fixed-order polynomial model.
Journal ArticleDOI
Improved Global Range Alignment for ISAR
Junfeng Wang,Xingzhao Liu +1 more
TL;DR: An improved global range alignment is presented for inverse synthetic aperture radar (ISAR) imaging, and the coefficients of this polynomial are chosen to optimize a quality measure of range alignment.
Journal ArticleDOI
Nonlinear frequency scaling algorithm for high squint spotlight SAR data processing
Lihua Jin,Xingzhao Liu +1 more
TL;DR: A new approach for the squint-mode spotlight SAR imaging that starts with the received signal dechirped in range and is processed by a nonlinear frequency scaling operation, which is different from the original frequency scaling one.
