A Novel Airborne Dual-Antenna InSAR Calibration Method for Backprojection Imaging Model
IEEE Access, 2021 The interferometric synthetic aperture radar (InSAR) elevation inversion method based on the backprojection (BP) imaging model simplifies the interferometric processing chain where image registration and phase unwrapping are not required.

Satellite-Based Evapotranspiration in Hydrological Model Calibration
Remote Sensing, 2020 Hydrological models are usually calibrated against observed streamflow (Qobs), which is not applicable for ungauged river basins. A few studies have exploited remotely sensed evapotranspiration (ETRS) for model calibration but their effectiveness on ...

Optimization of Semiautomated Calibration Algorithm of Multichannel Electrotactile Feedback for Myoelectric Hand Prosthesis [PDF]
, 2019 The main drawback of the commercially available myoelectric hand prostheses is the absence of somatosensory feedback. We recently developed a feedback interface for multiple degrees of freedom myoelectric prosthesis that allows proprioceptive and sensory

Phase and Baseline Calibration for Microwave Interferometric Radiometers Using Beacons [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2020 The relative phase and amplitude calibration between individual receiving elements are one of the key challenges in interferometric microwave radiometry. For monolithic interferometers, for example the Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) on board the Soil Moisture and Ocean Salinity (SMOS) mission, the calibration of these two ...

Multi-source self-calibration: Unveiling the microJy population of compact radio sources [PDF]
, 2016 Context. Very Long Baseline Interferometry (VLBI) data are extremely sensitive to the phase stability of the VLBI array. This is especially important when we reach {\mu}Jy r.m.s. sensitivities.
