Abstract. The planned and potential introduction in global satellite observing systems of conically scanning Ka- W-band atmospheric radars (e.g., the Tomorrow.IO constellation, https://www.tomorrow.io/space/, last access: 1 June 2022, Wivern (WInd VElocity Radar Nephoscope) radar, https://www.wivern.polito.it, July 2022) calls for development methodologies calibrating cross-calibrating these sy...

Near-infrared reflectance spectroscopy (NIRS) analysis is based on the development of calibration equations that relate constituents and the infrared information spectrum. This study compares 2 chemometric tools for developing NIRS prediction models: the GLOBAL modified partial least squares and the recently calibration strategy known as LOCAL. The LOCAL procedure is designed to select, from a ...

The design and calibration of the cross-correlator are crucial issues for interferometric imaging systems. In this paper, an analog complex cross-correlator with output DC offsets and amplitudes calibration capability is proposed for interferometric passive millimeter-wave security sensing applications. By employing digital potentiometers in the low frequency amplification circuits of the corre...

The Advanced Land Observing Satellite (ALOS) was launched in 2006, carrying the Phased Array type L-band Synthetic Aperture Radar (PALSAR). Although three years have passed from the start of ALOS PALSAR observation, we know the PALSAR is in operation with greatly stability operation. However, we need to monitor its performance for the future sustainable operation in order to evaluate the tempor...

Parametric conditional copula models allow the copula parameters to vary with a set of covariates according to an unknown calibration function. In this paper we develop a flexible Bayesian method to estimate the calibration function of a bivariate conditional copula. We construct a prior distribution over the set of smooth calibration functions using a sparse Gaussian process (GP) prior for the...

In this paper we present a method for combining data from an RGB camera, a long-wave-infrared (LWIR) thermal camera, and a LIDAR to obtain a registered RGB-depththermal (RGBDT) point cloud. Our method assumes that the intrinsic parameters of the cameras are known. For geometric calibration of the thermal camera, we discuss the calibration target used. For cross-calibration, our method requires ...

GSICS-Related Publication For the solar reflective channels, more than one vicarious method is often applied to enhance the confidence to interpret the sensor in-orbit performance by cross-checking the calibration results. Multiple vicarious calibration methods have been examined at NOAA/NESDIS/STAR for GOES Imager visible data using various stable targets including Desert, Deep Convective Clou...

Cosmic Ray Tau Neutrino Telescopes (CRTNT) using for sub-EeV cosmic ray measurement is discussed. Performances of a stereoscope configuration of a tower of those telescopes plus two side-triggers are studied by using a detailed detector simulation driven by Corsika. Detector aperture as a function of shower energy above 10 eV is calculated. Event rate of about 20k per year for the second knee m...

In this paper we discuss the radiometric calibration of dual polarimetric Synthetic Aperture Radar (SAR) data. The polarimetric distortion model of a dualpol SAR includes four calibration complex parameters: the cross-talk on transmit, the receiving channel imbalance and two receiving cross-talks. While these parameters can be estimated in a full-pol system using distributed targets with reflec...
