All details about data provision and availability, data access conditions, usage restrictions and the quota assignment procedure are described in the Terms of Applicability document available in the Resources section.

In Extended High beam mode six positions, EH1 to EH6, are available for collection of data in the 49 to 60 degree incidence angle range. Since this beam mode operates outside the optimum scan angle range of the SAR antenna, some minor degradation of image quality can be expected when compared with the Standard beam mode. Swath widths are restricted to a nominal 80 km for the inner three positions, and 70 km for the outer three positions.

In ScanSAR mode, combinations of two, three or four single beams are used during data collection. Each beam is selected sequentially so that data is collected from a wider swath than possible with a single beam. The beam switching rates are chosen to ensure at least one "look" at the Earth's surface for each beam within the along track illumination time or dwell time of the antenna beam. In practice, the radar beam switching is adjusted to provide two looks per beam. The beam multiplexing inherent in ScanSAR operation reduces the effective sampling rate within each of the component beams; hence the increased swath coverage is obtained at the expense of spatial resolution. The ScanSAR Narrow mode combines two beams (incidence angle range of 20 to 39 degrees) or three beams (incidence angle from 31 to 46 degrees) and provides coverage of a nominal 300 km ground swath, with spatial resolution of 50 m. The ScanSAR Wide mode combines four beams, provides coverage of either 500 km (with incidence angle range of 20 to 49 degrees) or 450 km (incidence angle range from 20 to 46 degrees) nominal ground swaths depending on the beam combination.

The Wide Standard Quad Polarization Beam Mode operates the same way as the Standard Quad Polarization Beam Mode but with higher data acquisition rates, and offers wider swaths of approximately 50 km at equivalent spatial resolution. 21 beams are available covering any area from 18 degrees to 42 degrees, ensuring overlaps of about 50% between adjacent swaths.

The Wide Fine Quad Polarization Beam Mode operates the same way as the Fine Quad Polarization Beam Mode but with higher data acquisition rates, and offers a wider swath of approximately 50 km at equivalent spatial resolution. 21 beams are available covering any area from 18 degrees to 42 degrees, ensuring overlaps of about 50% between adjacent swaths.

The Multi-Look Fine Resolution Beam Mode covers the same swaths as the Fine Resolution Beam Mode. Products with multiple looks in range and azimuth are generated at approximately the same spatial resolution as Fine Resolution Beam mode products, but with multiple looks and therefore improved radiometric resolution. Single look products are generated at finer spatial resolutions than Fine Resolution Beam Mode products. In order to obtain the multiple looks without a reduction in swath width, this beam mode operates with higher data acquisition rates and noise levels than Fine Resolution Beam Mode. As with the Fine Resolution Beam Mode, nine physical beams are available to cover the incidence angle range from 30 to 50 degrees, and additional near and/or far range swath positioning choices are available to provide additional overlap.

The Wide Multi-Look Fine Resolution Beam Mode offers a wider coverage alternative to the regular Multi-Look Fine Beam Mode, while preserving the same spatial and radiometric resolution, but at the expense of higher data compression ratios (which leads to higher signal-dependent noise levels). The nominal swath width is 90 km compared to 50 km for the Multi-Look Fine Beam Mode. The nine physical beams are the same as in the Multi-Look Fine Beam Mode, covering incidence angles from approximately 30 to 50 degrees, but the additional near and far range swath positioning choices available in the Multi-Look Fine Beam Mode are not needed because the beam centered swaths are wide enough to overlap by more than 50%.

The Wide Ultra-Fine Resolution Beam Mode provides the same spatial resolution as the Ultra-Fine mode as well as wider coverage, but at the expense of higher data compression ratios (which leads to higher signal-dependent noise levels). The set of Wide Ultra-Fine Resolution Beams cover any area within the incidence angle range from 30 to 50 degrees. Each beam within the set images a swath width of approximately 50 km.

The Extra-Fine Resolution Beam Mode nominally provides similar swath width and incidence angle coverage as the Wide Fine Beam Mode, at even finer resolutions, but with higher data compression ratios and noise levels. The four Extra-Fine beams provide coverage of swaths of approximately 160 km, 124 km, 120 km and 108 km in width respectively, and collectively span a total incidence angle range from 22 to 49 degrees. This beam mode also offers additional optional processing parameter selections that allow for reduced-bandwidth single-look products, 4-look, and 28-look products.

Specific restrictions to the use of data may apply for TPMs according to the terms of applicability valid for each mission. Utilisation of this data is subject to ESA's Earth Observation Terms and Conditions.

RADARSAT-1 was Canada's first commercial Earth observation satellite. It utilized synthetic aperture radar (SAR) to obtain images of the Earth's surface to manage natural resources and monitor global climate change. As of March 2013, the satellite was declared non-operational and is no longer collecting data.

NASA provided the Delta II launch vehicle to launch RADARSAT-1 and access to the NASA Deep Space Network (NASA DSN) in exchange for access to its data. Estimates are that the project, excluding launch, cost CA$620 million. The Canadian federal government contributed about CA$500 million, the four participating provinces (Qubec, Ontario, Saskatchewan and British Columbia) about CA$57 million, and the private sector about CA$63 million.

RADARSAT International, Inc. (RSI), a Canadian private company, was created in 1989 to process, market and distribute RADARSAT-1 data. (RADARSAT International, Inc. (RSI) was later acquired by MacDonald Dettwiler and Associates.) In 2006, RSI was rebranded MDA Geospatial Services International or MDA GSI.

On 29 March 2013, RADARSAT-1 experienced a technical problem. The Canadian Space Agency (CSA) assembled a team of engineers, who conducted an extensive investigation. Following numerous attempts to resolve the problem, the CSA, in consultation with its commercial data distributor MDA Geospatial Services Inc. concluded that RADARSAT-1 was no longer operational.[7]

I'm trying to learn SAR imagery processing with ArcGIS Pro. How can I import Radarsat-1 data into a mosaic dataset? Or is this option only available for Radarsat-2 data? The Canadian government has recently released RS-1 data to the public for free and wanted to give it a try.

Only some of the data has been 'pre-packaged' for generic use as .tiff files. As you can see from that website, there is very limited areas. I was talking about data I obtained from the EODMS portal from the CSA. Does anyone know how to add CEOS format data to arcgis?

The data comes with five files with five different extensions NVOL, SART, SARL, SOL, SARD. I know arcgis says they natively support RS-2 data. Perhaps I just need to convert CEOS format to RS-2 format.... but I don't know how...

Anyone who has registered with the NASA Earthdata login system and agreed to the ASF end user license agreement can now download Radarsat-1 data from the ASF DAAC.

The Alaska Satellite Facility is a part of the University of Alaska Fairbanks Geophysical Institute. ASF operates six satellite dish antennas, four of them for NASA, that downlink Earth-observing remote sensing data from polar-orbiting government and commercial satellites. Among those antennas is the iconic blue dish atop the UAF Elvey Building, home of the Geophysical Institute.

Ground support for the mission was provided by NASA through its ASF and McMurdo, Antarctica, tracking facilities. Through an agreement between CSA and the U.S. government, synthetic aperture radar data acquired by Radarsat-1 and downlinked at the NASA ground stations were processed and archived at ASF. The satellite mission ended in 2013.

CSA and NASA have cooperated since the beginning of the satellite mission to distribute processed synthetic aperture radar data through ASF, primarily to U.S. Earth science researchers. The recent agreement between CSA and NASA now makes these data freely available to the global research community.

Since it was established by an Act of Congress in 1946, scientists at the Geophysical Institute have studied geophysical processes from the center of the Earth to the surface of the sun and beyond, turning data and observations into information useful for state, Arctic and national priorities.

RADARSAT-1 was a C-Band (5.6cm wavelength) radar satellite launched 1995 in collaboration of MDA and the Canadian Space Agency. It is able to send and receive in horizontally polarized microwaves at a spatial resolution between 1m and 100m, and swath widths ranging from 18km - 500km, depending on beam mode. RADARSAT-1 went out of commission in 2013 after 17 years of supplying Canada and the world with reliable SAR data. It was Canada's first Earth observation satellite and was used across the country for tasks such as quantifying climate change, crop monitoring, marine hazard study, and disaster relief.
