Ground Clutter and Noise Mitigation Based on Range–Doppler Spectral Processing for Polarimetric Weather Radar

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Spectral polarization filtering in the range–Doppler domain plays an important role in weather radar clutter mitigation. However, when ground clutter and precipitation overlap, these methods tend to filter out clutter-contaminated precipitation ...

A Priori Knowledge Based Ground Moving Target Indication Technique Applied to Distributed Spaceborne SAR System

open access: yesRemote Sensing, 2023
Through formation flying, the distributed spaceborne SAR(synthetic aperture radar) system can increase the number of spatial degree of freedoms (DOFs) and provide flexible multi-baselines for SAR-GMTI (ground moving target indication), which improves the

Proposal Flow [PDF]

open access: yes, 2016
Finding image correspondences remains a challenging problem in the presence of intra-class variations and large changes in scene layout.~Semantic flow methods are designed to handle images depicting different instances of the same object or scene ...

Bearing-only acoustic tracking of moving speakers for robot audition [PDF]

open access: yes, 2015
This paper focuses on speaker tracking in robot audition for human-robot interaction. Using only acoustic signals, speaker tracking in enclosed spaces is subject to missing detections and spurious clutter measurements due to speech inactivity ...

MIMO radar space–time adaptive processing using prolate spheroidal wave functions [PDF]

open access: yes, 2008
In the traditional transmitting beamforming radar system, the transmitting antennas send coherent waveforms which form a highly focused beam. In the multiple-input multiple-output (MIMO) radar system, the transmitter sends noncoherent (possibly ...

SFNet: Learning Object-aware Semantic Correspondence [PDF]

open access: yes, 2019
We address the problem of semantic correspondence, that is, establishing a dense flow field between images depicting different instances of the same object or scene category.
