Compact polarimetry for automotive applications
International Journal of Microwave and Wireless Technologies, 2019AbstractThough 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

A Tool for Analysis and Calibration of Compact Polarimetry SAR Mode Anomaly
IEEE Geoscience and Remote Sensing Letters, 2018Transmit wave polarization (i.e., ellipticity and roll) deviation from the ideal or intended transmit mode affects compact polarimetry (CP) products and associated data exploitation. Hence, it is important to evaluate such effects on the CP model and account for the associated variations through data exploitations.

On the ship detection performance with compact polarimetry
2011 IEEE RadarCon (RADAR), 2011This 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 ...

A Simulation Study of Compact Polarimetry for Radar Retrieval of Soil Moisture
IEEE Transactions on Geoscience and Remote Sensing, 2014A 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.

Compact Polarimetry Mode for a Low Frequency SAR in Space
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008In 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 ...

Evaluating compact SAR polarimetry for tropical forest monitoring
Proceedings of SPIE, 2015Fully 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.

Assessment of compact polarimetry over different tropical environment and dataset
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010This paper presents different radar polarimetric modes over different study sites in Tropical environment: Full polarimetry (FP), Dual Polarimetry (DP) and Compact Polarimetry (CP). By using SVM classification, we show the capabilities of each polarimetric mode linked to the scattering model assumption of the fully polarimetric reconstruction for CP ...

Target Detection on the Ocean With the Relative Phase of Compact Polarimetry SAR
IEEE Transactions on Geoscience and Remote Sensing, 2013This paper discusses the potential for automatic ocean surveillance using compact linear polarization (CL-pol) synthetic aperture radar (SAR), with large area coverage. Here, the target is a wind farm in the North Sea. The relative phase, as derived from CL-pol SAR, is employed for detection of the wind turbines, apart from the wind turbines' wakes ...

Potential assessment of SAR in compact and full polarimetry mode for snow detection
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011This paper presents the comparison between the potential of SAR data in compact polarimetry (CP) and full polarimetry mode for snow detection. Eigenvalues based analysis and developed procedure have been used for this inter-comparison. It has been found over the part of rugged Siachen glaciated terrain, Indian Himalaya that dual polarization and ...

Compact antenna element for high‐resolution SAR polarimetry applications
Electronics Letters, 2013 For high‐resolution synthetic aperture radar polarimetry applications, a compact broadband dual‐polarised antenna element with high port isolation and low cross‐polarisation is investigated. The size of the element is 19 × 19 × 40 mm, which is much smaller than the traditional dual‐polarised horn.
