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

    The STRIPMAP HIMAGE main characteristics are summarised in the following table:

    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, multilooking 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 multilooked
    • Level 1C/1D - Geocoded product: GEC (level 1C product) and GTC (level 1D product)
      Obtained projecting the 1A product onto a regular grid in a chosen cartographic reference system. In case of Level 1C the surface is the Earth ellipsoid while for the Level 1D a DEM (Digital Elevation Model) is used to approximate the real Earth surface.
      In Level 1D data is constituted by the Backscattering coefficient of the observed scene, multilooked (except for Spotlight Mode), including the annexed Incidence Angles Mask.
