Study on the Use and Characteristics of SAR (Synthetic Aperture Radar) for Geological Applications. Part 2. Radargrammetry Aspects

摘要

The influence of imaging and flight parameters relevant in geological applications, such as the elevation angle and the flight direction, was investigated using radar imagery from experiments and simulated data. A geologically interesting test area was chosen to suggest processing algorithms for the creation of radar ortho images as a step to merge radar images to other data sets (e.g., data from geological maps) and subsequent nonlinear feature extraction. A method to create a digital elevation model from radar stereo images is presented. The influence of elevation angle and flight direction on the data quantity and quality is proved using a simulator.
