COmpact Polarimetry Potentials

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
The goal of this study is to show the potential of a compact-ol SAR system for vegetation applications. Compact-pol concept has been suggested to minimize the system design while maximize the information and is declined as the pi/4, pi/2 and hybrid modes.

Compact Polarimetry SAR and Compact Polarimetric SAR Interferometry

2021
Polarimetric SAR can obtain more abundant target information compared to ordinary single-polarized synthetic aperture radar. However, the addition of polarimetric ability increases the complexity of SAR system greatly, which imposes demanding requirements for antenna technology, data download rate, and power consumption.

Estimation of the degree of polarization in compact polarimetry

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The degree of polarization (DoP) has long been recognized as one of the most important parameters characterizing partially polarized electromagnetic waves. This parameter can be effectively used to describe the information content of polarimetric images collected by synthetic aperture radar (SAR) systems. Estimation of DoP is standardly performed using

Compact polarimetry for automotive applications

International Journal of Microwave and Wireless Technologies, 2019
AbstractThough compact polarimetric approaches have been developed and applied in space and geo researching systems they have not been taken into consideration in automotive applications, yet. A sensor system has been designed to conduct polarimetric measurements in the 77 GHz frequency band, which is permitted for automotive usage. This system is able

On the ship detection performance with compact polarimetry

2011 IEEE RadarCon (RADAR), 2011
This paper examines the performance of compact polarimetry (CP) for ship detection. An improved polarimetric information reconstruction algorithm is proposed based on a modified four-component model-based decomposition. The helix scattering component is considered in the reconstruction procedure to deal with the case when reflection symmetry condition ...

On the use of compact polarimetry SAR for ship detection

ISPRS Journal of Photogrammetry and Remote Sensing, 2013
Abstract Quad-pol data are generally acknowledged as providing the highest performance in ship detection applications using SAR data. Yet quad-pol data have half the swath width of single and dual-pol data and are thus less useful for maritime surveillance, where wide area coverage is crucial.

Compact Polarimetry Mode for a Low Frequency SAR in Space

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
In spaceborne SAR, a single-polarisation on transmit has, over full polarisation, the vast advantage of a double swath due to SAR system design issues. Without getting into the technical details deserving by themselves a full paper, we can just mention the swath characteristics of ALOS PALSAR, reducing from 70km for dual-pol mode to 30 km for full ...

The Compact Polarimetry Alternative for Spaceborne SAR at Low Frequency

IEEE Transactions on Geoscience and Remote Sensing, 2008
In spaceborne synthetic aperture radar (SAR), a single-polarization on-transmit offers twice the swath width compared to full polarization. This is linked to SAR system design issues, and, without getting into the technical details deserving by themselves a full paper, we can just mention the swath characteristics of ALOS PALSAR (the Advanced Land ...

Evaluating compact SAR polarimetry for tropical forest monitoring

Proceedings of SPIE, 2015
Fully polarimetric Synthetic Aperture Radar (SAR) or PolSAR has been proven useful for diverse applications related to environment. Nevertheless, problems are arising since satellite-borne PolSAR requires special arrangements on data acquisition and consumes higher energy for signal transmission.

A Simulation Study of Compact Polarimetry for Radar Retrieval of Soil Moisture

IEEE Transactions on Geoscience and Remote Sensing, 2014
A compact polarimetric (CP) radar system requires fewer measurements than a fully polarimetric (FP) system, thus allowing added flexibility in radar system design. Previous studies have shown the potential of using compact polarimetry for radar remote sensing of soil moisture.
