How does RADARSAT-2 improve on the remote sensing technology of RADARSAT-1?

How does RADARSAT-2 improve on the remote sensing technology of RADARSAT-1?

RADARSAT-2 provides several new imaging modes, such as polarimetric imagery (retrieval of full vectorial polarization information), ultra-fine (3 m resolution) beams, in addition to preserving all RADARSAT-1 modes.

Is RADARSAT-2 still active?

While RADARSAT-2 is still operational, an alternative and a successor was needed to respond to rapidly evolving needs. Fuelled by big data analytics and the growing use of artificial intelligence, among other things, the RCM is the next step for the RADARSAT Program, ensuring continuous data availability to users.

What does RADARSAT-2 do?

Ice and environmental monitoring, marine surveillance, disaster management, resource management and mapping.

How is RADARSAT used?

RADARSAT-1 collects data on resource management, ice, ocean and environmental monitoring and Arctic and off-shore surveillance. RADARSAT-1 carries an advanced Synthetic Aperture Radar (SAR) operating at 5.3 GHz (C-band).

Why is the RADARSAT important?

Canada has invested in radar satellites in the RADARSAT program because they can image the earth’s surface at any time, day or night, and through all conditions, such as smoke, clouds or any other type of weather. This function is crucial.

What are the applications of RADARSAT?

RADARSAT-2 applications

• Ice. The RADARSAT program was born out the need for effective monitoring of Canada’s icy waters.
• Marine surveillance. Credit: Canadian Coast Guard.
• Mapping. Map prepared by the Argentinian Space Agency (CONAE). (
• Agriculture.
• Forestry.

What did the RADARSAT discover?

5. What did RADARSAT-1 look for on the ocean surface? It provided information on features such as surface waves so we can better understand the oceans and their impact on our climate. These data were used by meteorological services, the fishing industry, and oceanographers.

Is Radarsat-2 free?

ESA, in collaboration with MDA, is offering free access to RADARSAT-1 and RADARSAT-2 data for research and development, both archived and new acquisitions for the following modes: ScanSAR Wide and Narrow (Single or Dual Pol) Wide (Single or Dual Pol)

What type of radar is used in Radarsat 2?

RADARSAT-2 uses C-band synthetic-aperture radar (SAR). Data may be acquired in any combination of horizontal and vertical polarizations (HH, HV, VV, VH). Resolution and swath width depends on the operation mode; the resolution range is 1 to 100 metres, and the swath width ranges from 18 to 500 kilometres.

What is RCM for RADARSAT-2?

The overall objective of RCM is to provide C-band SAR data continuity for the RADARSAT-2 users, as well as adding a new series of applications enabled through the constellation approach. The SAR imagery is required by various Canadian government users (including the Canadian Forces) at frequent revisit rates (high temporal resolution).

What is the future of RADARSAT?

– The future RCM (RADARSAT Constellation Mission) is the evolution of the RADARSAT Program with the objective of ensuring data continuity, improved operational use of SAR (Synthetic Aperture Radar) and improved system reliability. It is a constellation of three satellites providing around-the-clock coverage.

When did RADARSAT-2 arrive at DFL?

The subsystems arrived at the David Florida Laboratory (DFL) from 2003 to 2005 for assembly, integration and testing. Work at DFL and CSA preparations at Saint-Hubert, Quebec, were completed in September 2007. RADARSAT-2 arrived at Baikonur Cosmodrome by air on 15 November 2007 and launched on 14 December 2007.
