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.

Improved Threat Detection in Walk-Through Security Scanning Using an Optimized Polarimetric Target Decomposition Method

open access: yesIEEE Journal of Microwaves, 2023
Reliable and convenient walk-through security scanning, which doesn't separate people or impede their movement, is an extremely challenging task. In this paper, a novel approach for a security check with an overhead observation and a polarimetric ...

Ship and Oil-Spill Detection Using the Degree of Polarization in Linear and Hybrid/Compact Dual-Pol SAR [PDF]

open access: yes, 2012
Monitoring and detection of ships and oil spills using synthetic aperture radar (SAR) have received a considerable attention over the past few years, notably due to the wide area coverage and day and night all-weather capabilities of SAR systems.

Visualisation and interpretation of PolSAR data based on polarimetric coherence

open access: yesThe Journal of Engineering, 2019
Polarimetric coherence strongly relates to the target scattering characteristics. Coherences of different second-order statistics show different advantages in target discrimination in specific correspondence to physical scattering mechanism.

Airborne polarimetric Doppler weather radar: trade-offs between various engineering specifications [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2018
NCAR EOL is investigating potential configurations for the next-generation airborne phased array radar (APAR) that is capable of retrieving dynamic and microphysical characteristics of clouds and precipitation. The APAR will operate at C band.

Polarimetric Doppler Weather Radar [PDF]

open access: yesEos, Transactions American Geophysical Union, 2002
Weather radar has been used by meteorologists throughout the world since the 1940s as a valuable remote sensing technology. A significant milestone was reached in the late 1980s when the first of a network of 158 Weather Surveillance Radar‐1988 Doppler (WSR‐88D) weather radars was installed in central Oklahoma.
