Processing Algorithms

• Processing data obtained both in StripMap (single-beam) and ScanSAR (multi-beam) mode
  
• Generating integer and complex output products
  
• Possibility to select an image segment for synthesis, specifying a UTC time window
  
• Efficient processing stages: raw data correction, range compression with range migration correction, Doppler estimation, azimuth compression
  with optional multi-look processing, image geolocation using satellite ephemeris data
  
• Flexible choice of processing algorithms and the relevant processing techniques
  
• High-accuracy algorithm for focusing the radar hologram in frequency domain
  
• Unique technique of Doppler frequency estimation using on both processed hologram and platform location data
  
• Automatic Doppler analysis uses MLBF, MLCC, CDE, SDE algorithms for high accuracy of Doppler estimation
  
• Manual correction for the Doppler values throw image
  
• Sophisticated algorithms of Doppler estimation to handle subtle problems causing imagery “scalloping” and “banding”
  
• Radar images combined synthesis for further interferometric processing
  
• Elimination of the image brightness distortions caused by the narrow dynamic range of the onboard analog-to-digital converter
  
• Support of ground-range geometry, multi-looked and detected images for standard image processing
  
• Image radiometric corrections: surface type, antenna pattern, slant range variations, along track gain variations, azimuth and range reference, used for signal focusing
  

RDC ScanEx also offers ScanMagic(R) software as a companion tool to SSARP for easy-to-use visualization, comprehensive image analysis and custom processing capabilities. ScanMagic fully supports all the SSARP generated Level-1 SAR products and enables user to create value-added geolocated RADARSAT products on the same Windows workstation just in a few mouse clicks.
