Synthetic Aperture Radar Radiometric Cross Calibration Based on Distributed Targets

IEEE 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 ...

The cross-calibration array: a technique to cross-calibrate the energy scales of cosmic-ray experiments using a portable radio array

Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023), 2023
The sources of the highest energy cosmic-rays are still a mystery. One way to try to understand these sources is to measure the energies and composition of cosmic rays and build models that describe their energy spectrum. However, at the highest energies, energy scales between experiments are inconsistent.
