Journal ArticleDOI
Ship and Oil-Spill Detection Using the Degree of Polarization in Linear and Hybrid/Compact Dual-Pol SAR
TL;DR: The degree of polarization (DoP) is a fundamental quantity characterizing a partially polarized electromagnetic field, with significantly less computational complexity, readily adaptable for on-board implementation, compared with other well-known polarimetric discriminators.
Journal ArticleDOI
Mechanical Load Fault Detection in Induction Motors by Stator Current Time-Frequency Analysis
TL;DR: In this article, the authors examined the detection of mechanical faults in induction motors by an original use of stator current time-frequency analysis, which leads generally to periodic load torque oscillations.
Journal ArticleDOI
On-Line Monitoring of Mechanical Faults in Variable-Speed Induction Motor Drives Using the Wigner Distribution
TL;DR: This paper proposes the use of a time-frequency distribution, the Wigner Distribution, for stator current analysis, and results in a steady-state and during transients with load torque oscillations and load imbalance are presented.
Journal ArticleDOI
A New Multivariate Statistical Model for Change Detection in Images Acquired by Homogeneous and Heterogeneous Sensors
TL;DR: This paper proposes a new approach for similarity measurement between images acquired by heterogeneous sensors that exploits the considered sensor physical properties and specially the associated measurement noise models and local joint distributions.
Journal ArticleDOI
Hilbert versus Concordia transform for three-phase machine stator current time-frequency monitoring
Baptiste Trajin,Baptiste Trajin,Marie Chabert,Jeremi Regnier,Jeremi Regnier,Jean Faucher,Jean Faucher +6 more
TL;DR: In this article, the authors proposed an alternative complex signal representation which takes advantage of the three stator current measurements available in a three-phase machine, which unconditionally allows separate modulation diagnosis under Bedrosian conditions.
