Intercomparison of simulations using 5 WRF microphysical schemes with dual-Polarization data for a German squall line [PDF]

open access: yesAdvances in Geosciences, 2008
Simulations of a squall line system which occurred on 12 August 2004 near Munich, Germany are performed using a fine grid version of the Weather Research and Forecasting (WRF) model with five different microphysical schemes.

A Quality Control Concept for Radar Reflectivity, Polarimetric Parameters, and Doppler Velocity [PDF]

open access: yes, 2006
Over the last few years the use of weather radar data has become a fundamental part of various applications like rain-rate estimation, nowcasting of severe weather events, and assimilation into numerical weather prediction models.

Experimental validations of insect orientation extraction based on fully polarimetric measurement

open access: yesThe Journal of Engineering, 2019
The purpose of this study is to demonstrate that the fully polarimetric radar can be effectively used to measure the insect orientation. First, the polarisation scattering matrix (PSM)-based orientation extraction method is reviewed.

Polarimetric optimisation in radar interferometry

open access: yesElectronics Letters, 1997
A general formulation for vector wave interferometry is outlined and the optimisation problem is then solved, involving maximisation of the phase coherence. In this way it is shown that wave polarisation effects play an important role in the extraction of information from radar interferograms.

Multibaseline Polarimetric SAR Interferometry Coherence Optimization [PDF]

open access: yes, 2008
This letter analyzes different approaches for polarimetric optimization of multibaseline (MB) interferometric coherences. Two general methods are developed to simultaneously optimize coherences for more than two data sets. The first method provides every

Polarimetric Calibration for a Ground-Based Radar, and Comparison of the Polarimetric Parameters with Air-Borne SAR Obtained from a Forest

open access: yesRemote Sensing, 2017
A polarimetric ground-based radar (GB-radar) system operated in the L-band has been developed. The frequency range of GB-radar is 1.215 to 1.3 GHz, which is the same as that of Japanese satellite-borne SAR, PALSAR-2 (Phased Array type L-band Synthetic ...

Polarimetric calibration strategy for long-duration imaging with a ground-based SAR [PDF]

open access: yes, 2005
The Ground-Based Synthetic Aperture Radar (GB-SAR) facility in the UK provides high-resolution, fully polarimetrically calibrated L- through X-band SAR imagery, principally of targets of remote sensing interest such as soils and vegetation.
