Abstract :
The high resolution distributed SAR satellites provide the chance to derive DEMs with submeter accuracy (HRTI-4) on local or even regional scale, which can be called Very Large Baseline Interferometry (VLBI). This paper presented a survey of the signal processing flow chart for VLBI. Performance prediction and analysis were based on error contributions as absolute phase estimation error and baseline measurement error, and so on. The simulation experimental results assure the effectiveness of the processing techniques.
