Radiometric-Waveguide Calibrators
IEEE Transactions on Instrumentation and Measurement, 2007We describe the electromagnetic and thermal design, performance, and fabrication for two types of radiometric- waveguide load calibrators. A simple theory is presented and used to minimize the total volume of the absorber structure. These devices have been used from room temperature to below 4 K in microwave to millimeter wavebands.

Proceedings. 1999 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (Cat. No PR00149), 2003
A simple algorithm is described that computes the radiometric response function of an imaging system, from images of an arbitrary scene taken using different exposures. The exposure is varied by changing either the aperture setting or the shutter speed. The algorithm does not require precise estimates of the exposures used.

Radiometric Cross-Calibration of the ZY1-02D Hyperspectral Imager Using the GF-5 AHSI Imager
IEEE Transactions on Geoscience and Remote Sensing, 2022The ZY1-02D satellite, which was launched in 2019, is China’s first civil hyperspectral satellite. However, the laboratory calibration and vicarious calibration methods could not provide accurate radiometric calibration coefficients after the satellite ...

Self-Calibrating Polarising Radiometric Calibration
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018We present a self-calibrating polarising radiometric calibration method. From a set of images taken from a single viewpoint under different unknown polarising angles, we recover the inverse camera response function and the polarising angles relative to the first angle.

Radiometric Calibration of a Hyperspectral Microwave Sounder
2023 48th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2023Hyperspectral microwave sounding of atmospheric temperature and humidity profiles is a promising application for spaceborne weather observation. This approach extends the capabilities of more traditional infrared sounders to include incloud retrievals, significantly expanding the observational scope of the remote sensing technique.

PALSAR Radiometric and Geometric Calibration
IEEE Transactions on Geoscience and Remote Sensing, 2009This paper summarizes the results obtained from geometric and radiometric calibrations of the Phased-Array L-Band Synthetic Aperture Radar (PALSAR) on the Advanced Land Observing Satellite, which has been in space for three years. All of the imaging modes of the PALSAR, i.e., single, dual, and full polarimetric strip modes and scanning synthetic ...

Hawkeye radiometric calibration methodology
Earth Observing Systems XXIII, 2018Hawkeye is an ocean color instrument designed, manufactured and characterized at Cloud land Instruments, CA. It is a push broom instrument that has 8spectral bands similar to SeaWiFS and a spatial resolution of 120 m. Each spectral band has 1800 detectors (pixels) and all 14,000 detectors (pixels) need to be calibrated independently.
