blue arrow DESCRIPTION

ICEYE full archive and new tasking products are available in StripMap, SpotLight and SpotLight SAR modes, SLC and GRD processing levels:

  • SpotLight instrument mode: mechanical antenna steering in the azimuth direction towards an aim point on the ground is used to increase the illumination time, resulting in an increased synthetic aperture and, therefore, better azimuth resolution compared to a continuous stripmap mode. The standard Spotlight mode uses a 300MHz transmitted pulse bandwidth to provide a slant plane image that has a resolution of 0.5 m, which is translated into a ground plane image that extends 5 km x 5 km with a ground resolution (after multi looking) of 1 m x 1 m.
  • Spotlight High instrument mode: the satellite agility allows to point forwards and backwards towards a target area by a more-than-conventional amount, to obtain an extended Synthetic aperture length and to provide a slant plane image with a resolution of 0.5 m (range) by 0.25 m (azimuth); when translated into the ground, the products has 1 m resolution with an area of 5 km x 5 km but due to multi-looking, speckle noise is significantly reduced.
  • StripMap instrument mode: the ground swath is illuminated with a continuous sequence of pulses while the antenna beam is fixed in elevation and azimuth. This results in an image strip with a continuous image quality in the flight direction. The standard Stripmap mode adjusts the transmitted pulse bandwidth to always achieve a ground range resolution of 3 m. In the Stripmap High mode, the transmitted pulse bandwidth is set to be the maximum of 300MHz in order to provides a slant range resolution of 0.5 m and an azimuth resolution of 2.5 to 3 m depending on incidence angle.

Two different processing levels can be requested:

  • Single Look Complex (SLC): Single Look Complex (SLC) Level 1a products consist of focused SAR data geo-referenced using orbit and attitude data from the satellite and the scenes are stored in the satellite's native image acquisition geometry which is the slant-range-by-azimuth imaging plane and with zero-Doppler SAR coordinates. The pixels are spaced equidistant in azimuth and in slant range. The products include a single look in each dimension using the full transmit signal bandwidth and consist of complex magnitude value samples preserving both both amplitude and phase information.
    No radiometric artefacts induced by spatial resampling or geocoding.
    The product is provided in Hierarchical Data Format (HDF5) plus a xml file with selected metadata
  • Ground Range Detected (GRD): Ground Range Detected (GRD) Level 1b products consist of focused SAR data that has been detected, multi-looked and projected to ground range using an Earth ellipsoid model. The image coordinates are oriented along the flight direction and along the ground range. Pixel values represent detected magnitude, the phase information is lost. The resulting product has approximately square spatial resolution pixels and square pixel spacing with reduced speckle due to the multi-look processing at the cost of worse spatial resolution.
    No image rotation to a map coordinate system has been performed and interpolation artefacts are thus avoided.
    The product is provided in GeoTiff plus a xml file with selected metadata
