Impact of cross‐polarization isolation on polarimetric target decomposition and target detection

Radio Science, 2015
AbstractCross‐polarization isolation is one of the key engineering parameters for a polarimetric radar system. Previous studies focused more on the calibration of cross‐talk contamination. This paper presents a numerical evaluation of the requirement for cross‐polarization isolation from the data users' perspective, i.e., the quantitative impact of ...

Target Decomposition Based on Symmetric Scattering Model for Hybrid Polarization SAR Imagery

IEEE Geoscience and Remote Sensing Letters, 2021
The compact polarimetric (CP) imaging mode is a special, dual-polarization mode in which only one polarization is transmitted and two orthogonal polarizations are simultaneously used to measure the returns.

Subgraph decomposition for multi-target tracking

2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015
Tracking multiple targets in a video, based on a finite set of detection hypotheses, is a persistent problem in computer vision. A common strategy for tracking is to first select hypotheses spatially and then to link these over time while maintaining disjoint path constraints [14, 15, 24].

Target recognition using wavelets decomposition

IEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004
Radar target recognition continues to be a challenging problem which has yielded considerable algorithmic and hardware advances, particularly in military applications. It has been known for many years that the echo received from a remote object in response to illumination by a radar system is dependant on the nature and shape of the object, leading to ...

Target Polarimetric Decompositions of PolSAR Image

2021
Target polarimetric decomposition is one of the most important aspects of polarimetric microwave imaging. The objective of polarimetric decomposition is to express the polarimetric information of the target as a combination of many known objects, such as a plate, a dihedral, a helix, a line, and a sphere, so we can understand and analyze the scattering

Hyperspectral Time-Series Target Detection Based on Spectral Perception and Spatial–Temporal Tensor Decomposition

IEEE Transactions on Geoscience and Remote Sensing, 2023
The detection of camouflaged targets in the complex background is a hot topic of current research. The existing hyperspectral target detection algorithms do not take advantage of spatial information and rarely use temporal information. It is difficult to

Retrieval of Polarimetric Azimuthal Angular Characteristics via the Application of Target Decomposition to Spectral Domain Circular SAR Images

IEEE Transactions on Geoscience and Remote Sensing, 2019
In this paper, we discuss the application of polarimetric target decomposition (TD) theorems to circular synthetic aperture radar (CSAR) images to retrieve the polarimetric azimuthal angular characteristics of the targets. In CSAR systems, radar-carrying

Infrared Small Target Detection via Nonconvex Tensor Tucker Decomposition With Factor Prior

IEEE Transactions on Geoscience and Remote Sensing, 2023
Infrared small target detection in complex scenes is an important but challenging research hotspot in infrared early warning fields. Previous studies have proved that low-rank Tucker decomposition (TD) achieves good detection performance in complex ...

Unified phenomenological decomposition of Radar Targets

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Huynen phenomenological decomposition as the first formalized target decomposition has not been widely accepted. Huynen's preference for scattering symmetry and regularity restricts not only the application of this decomposition but also its unification with other target dichotomies such as the Barnes-Holm decomposition and Yang decomposition.
