Interpretation of SAR Imagery

  • Ravi P. GuptaEmail author


The technique of SAR imaging and the various aerial and space-borne SAR sensors have been discussed in the preceding chapter. The radar response opens up new avenues for discriminating and mapping Earth materials, as the radar signal provides a ‘new look’ at the ground. SAR images possess a different type of geometric distortion, and therefore due care and expertise are required. Factors affecting SAR signal include: power transmitted, antenna gain, radar wavelength, beam polarization, look angle, aspect angle, slant range, and ground surface characteristics, particularly surface roughness and complex dielectric constant. Polarimetry and SAR tomography are new emerging techniques.
