Journal ArticleDOI
Imaging of a Moving Target With Rotating Parts Based on the Hough Transform
TL;DR: An imaging method for moving targets with rotating parts is presented that is simple to implement and is based on the Hough transform (HT), which is widely used in image processing.
Journal ArticleDOI
Estimation of three-dimensional motion parameters in interferometric ISAR imaging
TL;DR: A three-dimensional (3-D) motion compensation method, or 3-D focusing, is put forward in this paper, with a multiple antenna pair configuration, where the angular motion parameters both in the azimuth and pitching directions are accurately estimated without the usual phase-unwrapping processing.
Journal ArticleDOI
Micro-Doppler Effect Analysis and Feature Extraction in ISAR Imaging With Stepped-Frequency Chirp Signals
TL;DR: The stepped-frequency chirp signal (SFCS) is used to synthesize the ultrabroad bandwidth and reduce the requirement of sample rates and the simulations validate the theoretical formulation and robustness of the proposed m-D extraction method.
Journal ArticleDOI
Three-Dimensional ISAR Imaging Based on Antenna Array
TL;DR: Two cross-range motion parameters measurement algorithms, one based on array processing of the range profile and another based on correlation of ISAR images of different antennas, are proposed and simulation results have shown the effectiveness of the proposed methods.
Journal ArticleDOI
Three-dimensional SAR imaging of a ground moving target using the InISAR technique
Qun Zhang,Tat Soon Yeo +1 more
TL;DR: This imaging method is based on the ISAR principle and the simple observation that all scatterers on a moving target move in tandem, thus avoiding phase-unwrapping processing and image-resampling processing as required by conventional methods.
