Ship surveillance with Radarsat-2 ScanSAR

SPIE Proceedings, 2014
Ship detection is a significant application of maritime monitoring and security. To fully explore the potential of wide coverage of synthetic aperture radar (SAR) image, the ScanSAR Wide image for ship detection is investigated in this paper. The Radarsat-2 ScanSAR Wide mode image is used as the image source due to its huge coverage and constant false ...

Alos and Radarsat Synergies in Geological Investigations

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
The combination of ALOS PALSAR and RADARSAT- 2 InSAR time series images improved the geological interpretation of ground deformation on vegetated slopes, and heaving from oil extraction. ALOS change detection techniques were used to monitor mining activities in a remote densely forested area.

RADARSAT application in ocean wind measurements

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
SAR can penetrate clouds and precipitation and can provide accurate observations of surface features such as fronts and localized coastal marine winds. Often atmosphere-ocean interaction processes evident in SAR imagery are not present from in situ observations, the operational network, weather prediction models, or scatterometer data, especially in ...

Countdown for RADARSAT-2 system operations

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
RADARSAT-1 has been operating for over nine years as the world's first commercial space-borne synthetic aperture radar (SAR) remote sensing system. RADARSAT-2 provides for a continuation of the RADARSAT-1 services, enhanced performance, new features, and a more commercial approach to both the development and operation of the system.

Radarsat Constellation, moving toward implementation

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The Canadian Space Agency initiated the development of a three-satellite SAR mission, known as the RADARSAT Constellation Mission (RCM), in 2005. The main objective of the mission is to assure C-band data continuity in the next decade, while allowing a greater use of data for operational applications by providing more persistent observation over Canada

SAR tomography development for Radarsat-2

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
Presently, a standard SAR image is obtained using two-dimensional information acquired in a single pass monostatic acquisition. The third dimension of the image is folded in the 2D space based on the range information. With the availability of large datasets acquired with high resolution and from slightly different positions it was shown that amplitude

RADARSAT for oil spill trajectory model

Environmental Modelling & Software, 2004
Abstract This work introduces a new approach for utilizing RADARSAT data for oil slick detection and oil slick trajectory model in the coastal water of Malacca Straits. The concept of the study involves two sub-models. The first model contains texture algorithms for oil slick automatic detection.

Image quality and calibration of RADARSAT-2

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
RADARSAT-2 has 177 operational imaging modes. Versions of each of these modes are available either for left-or right-looking imaging, and most modes allow images to be generated for any of the four linear polarization combinations (HH, VV, HV, VH). To support these modes there are currently 1816 sets of beam coefficients and 16 digitized pulse forms ...
