Synthetic Aperture Radar Radiometric Cross Calibration Based on Distributed Targets

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Synthetic aperture radar (SAR) radiometric calibration is an essential step in inferring meaningful physical information about the target. The majority of current calibration processes are directly based on artificial calibrators, but the number of ...

Self-Calibration of Neutrino Detectors using characteristic Backgrounds [PDF]

open access: yes, 2007
We introduce the possibility to use characteristic natural neutrino backgrounds, such as Geoneutrinos (\bar{\nu}_e) or solar neutrinos (\nu_e), with known spectral shape for the energy calibration of future neutrino detectors, e.g.

SiamCCF: Siamese visual tracking via cross‐layer calibration fusion

open access: yesIET Computer Vision, 2023
Siamese networks have attracted wide attention in visual tracking due to their competitive accuracy and speed. However, the existing Siamese trackers usually leverage a fixed linear aggregation of feature maps, which does not effectively fuse the ...

MASE: A New Data--Reduction Pipeline for the Magellan Echellette Spectrograph [PDF]

open access: yes, 2007
We introduce a data reduction package written in Interactive Data Language (IDL) for the Magellan Echellete Spectrograph (MAGE). MAGE is a medium-resolution (R ~4100), cross-dispersed, optical spectrograph, with coverage from ~3000-10000 Angstroms.
