    ScanSAR HUGE is one of the modes in which the COSMO-SkyMed SAR can operate, right and left looking acquisition.

    The ScanSAR HUGE main characteristics are summarised in the following table:

    Acquisition Mode
    Processing levels
    Level 1A
    (SCSB and SCSU)
    Level 1B (DGM)
    Level 1C (GEC)
    Level 1D (GTC)
    Ground Range resolution (m)
    Azimuth resolution (m)
    Range x Azimuth scene size (km)
    200 x 200
    Scene duration (sec)
    Geolocation ±3s accuracy (m)
    Number of looks

    Processing Levels:

    • Level 1A (1A_SCSB and 1A_SCSU)
    • Single-look Complex Slant product, RAW data focused in slant range-azimuth projection, that is the sensor natural acquisition projection; product contains In-Phase and Quadrature of the focused data, weighted and radiometrically equalised.
      The processing of the 1A_SCSU product differs from that of the 1A_SCSB product for the following features:
      • a non-weighted processing is performed, which means that windowing isn't applied on the processed bandwidth
      • radiometric equalisation (in terms of compensation of the range antenna pattern and incidence angle) is not performed; hence only compensation of the antenna transmitter gain and receiver attenuation and range spreading loss is applied
    • Level 1B (1B_DGM)
    • Detected Ground Multi-look product obtained detecting, multi-looking and projecting the COSMO-SkyMed products SAR Standard SAR Higher Level Auxiliary products Single-look Complex Slant data onto a grid regular in ground; Note: Spotlight Mode products are not multi-looked
    • Level 1C/1D - Geocoded product: GEC (1C level product) and GTC (1D level product)
    • Obtained projecting the 1A product onto a regular grid in a chosen cartographic reference system. In case of Lev 1C the surface is the earth ellipsoid while for the Lev 1D a DEM (Digital Elevation Model) is used to approximate the real earth surface.
      In Lev 1D data is constituted by the Backscattering coefficient of the observed scene, multi-looked (except for Spotlight Mode), including the annexed the Incidence Angles Mask.
