METHOD FOR PROCESSING HIGH-RESOLUTION SPACEBORNE SPOTLIGHT SAR RAW DATA

摘要

The invention relates to a method for processing high-resolution spotlight SAR raw data, comprising the adaptation of the range history to a hyperbolic shape suitable for the efficient SAR processing while taking into consideration a function for the geometric correction, numerically including the orbit shape actually measured using an azimuth-dependent phase correction (e.g. according to steps 3.3 and 3.4) and a function for correcting constant run-time effects in the troposphere, which effects are variable within the illumination time, and using a likewise azimuth-dependent phase correction (e.g. according to steps and 3.5, 3.6)
