Utilization of parallelization algorithms in inSAR/PS-InSAR processing

Abstract

This study describes a method for InSAR/PS-InSAR processing using parallelization algorithms. The InSAR/PS-InSAR processing chain is analyzed from the aspect of the computational load, which results in a specific parallelization model. The theoretical concept for the porting of Delft Object-oriented Radar Interferometric Software (Doris) into a parallel computational environment is described. The features of the presented parallelization model include efficient interprocessor communications utilized by MPI (Multi Passage Interface) and a "chained" data distribution capability. An example of the mapping process is illustrated for the case of simple InSAR processing.
