    ?Imaging Modes

    RADARSAT-2 is the most flexible, highest-capacity commercial SAR sensor, and provides customers in the oil and gas sector with a range of SAR imagery options for every application.

    ScanSAR Narrow

    SWATH WIDTH: 300 km
    POLARIZATION: Single or Dual

    The ScanSAR imaging modes provide images of very wide swaths in a single pass of the satellite, and are intended for use in applications requiring large area coverage.

    In the ScanSAR modes, two, three or four of the single physical beams covering adjoining swaths are used in combination. The beams are operated sequentially, each for a series of pulse transmissions and receptions, so that data are collected from a wider swath than is possible with a single beam. The beam switching rates are chosen to ensure that the blocks of imagery produced from successive sets of pulse returns from each beam provide unbroken along-track coverage. For the standard RADARSAT-2 ScanSAR modes, the radar beam switching has been chosen to provide two azimuth looks per beam for all points.

    ScanSAR Narrow is ideally suited for broad-area offshore monitoring as it combines the dual polarization to help with oil and vessel detection with 300 kilometre swath width to provide an overview of 90,000 km2. of ocean in a single image with a resolution ideal for the detection of oil slicks from all sources.

    Fine Quad-Pol

    Fine Quad-PolNOMINAL RESOLUTION: 8 m
    SWATH WIDTH: 25 km (50 km Wide Fine Quad Polarization)

    The Fine Quad Polarization Beam Mode provides full polarimetric imaging with the same spatial resolution as the Fine Resolution Beam Mode. Fine Quad Polarization Beam Mode products with swath widths of approximately 25 kilometre can be obtained covering any area within the region from an incidence angle of 18 degrees to at least 49 degrees.

    Fine Quad-Polarization is also available in a wide variant. The Wide Fine Quad Polarization mode operates the same way as the Fine Quad Polarization mode but with higher data acquisition rates, and offers a wider swath of approximately 50 kilometre at equivalent spatial resolution.

    Quad Polarized imagery from MDA offers the most complete information available from space-based radar. High-resolution Quad Polarized data enables quantitative analysis to better characterize and classify detected oil slicks.

    The imaging modes identified in this section are a representative sample of the 20 imaging modes available on RADARSAT-2, and have been highlighted for their applicability to Oil and Gas applications. A complete listing of all the RADARSAT-2 beam modes and their specifications, are available in the Satellites section of this site.
