A Comparison of Phantoms for Cross-Calibration of Lumbar Spine DXA
Osteoporosis International, 2002The aim of this project was to compare three phantoms used for cross-calibration of dual-energy X-ray absorptiometers with an in vivo cross-calibration. The phantoms used were the Bona Fide Phantom (BFP), the European Spine Phantom (ESP) and the GE Lunar Aluminum Spine Phantom (ASP). The cross calibration was for L2-L4 lumbar spine bone mineral density

Sensitivity and cross calibration
European Journal of Nuclear Medicine, 1989In Positron Emission Tomography it is possible to obtain quantitative information on the distribution of positron emitting radiopharmaceuticals. The different components influencing the sensitivity and the cross calibration of PET systems are discussed especially with respect to the quantitative nature of the PET technique.

A Satellite Cross-Calibration Experiment
IEEE Geoscience and Remote Sensing Letters, 2004Recently, the Advanced Earth Observing Satellite 2 (ADEOS-2) was launched (December 14, 2002) successfully, and the Global Imager (GLI) onboard the ADEOS-2 satellite became operational in April 2003. In a first calibration checkup, the radiometric performance of GLI was compared relatively to that of other sensors on different satellites with different

Cross calibration in longitudinal studies
Statistics in Medicine, 2004AbstractIn a long‐running longitudinal study using complex machinery to obtain measurements, it is sometimes necessary to replace the machine. This can result in lack of continuity in the measurements that can overwhelm any treatment effect or time trend.

Online cross-calibration of camera and LIDAR
2017 13th IEEE International Conference on Intelligent Computer Communication and Processing (ICCP), 2017In an autonomous driving system, drift can affect the sensor's position, introducing errors in the extrinsic calibration. For this reason, we have developed a method which continuously monitors two sensors, camera, and LIDAR with 16 beams, and adjusts the value of their cross-calibration.

Cross-calibration of ground and space radar
IEEE International Geoscience and Remote Sensing Symposium, 2003Presents results from comparing space radar and ground radar to cross-calibrate the Kwajalein polarimetric radar (KPOL) with the spaceborne TRMM Precipitation Radar (PR). Use of self-consistency of polarimetric measurements is implemented to check the absolute calibration of KPOL and is checked against the cross-calibration results of PR and KPOL ...

Truths cross-calibration uncertainty tool
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015This paper describes a set of tools, algorithms and methodologies that have been developed and used in order to estimate the radiometric uncertainty achievable for a Sentinel 2/3 like sensor through in-flight cross-calibration using a well-calibrated hyperspectral SI traceable reference sensor such as the proposed TRUTHS (Traceable Radiometry ...

Cross-calibration between airborne SAR sensors
IEEE Transactions on Geoscience and Remote Sensing, 1993A comparative study of data acquired by two different airborne synthetic aperture radar (SAR) sensors from the same site is presented. External, ground-target-based calibration has been performed on the NASA/JPL DC-8 SAR C-band data and the DLR E-SAR C-band data collected over the DLR test site in Oberpfaffenhofen.

Cross Calibration by FFT Equalization
Journal of Dynamic Systems, Measurement, and Control, 1997The classical calibration problem is primarily concerned with comparing an approximate measurement method with a very precise one. Frequently, both measurement methods are very noisy, so we cannot regard either method as giving the true value of the quantity being measured.

OCO/GOSAT Preflight Cross-Calibration Experiment
IEEE Transactions on Geoscience and Remote Sensing, 2010The Orbiting Carbon Observatory (OCO) by NASA's Jet Propulsion Laboratory (JPL) and Greenhouse gases Observing SATellite (GOSAT) by JAXA were built to provide independent measures of the global distributions of carbon dioxide (CO2) from space. GOSAT achieved a successful orbit on January 23, 2009, and OCO failed its launch attempt on February 24, 2009.
