Abstract :
This paper presents the framework for synthetic aperture radar raw data processing using high performance computing server. The multi-threads procedure for CS algorithm integrated motion compensation is presented based on the advanced framework of high performance computing server. Simulation results demonstrate that the processing time can be reduced significantly using multi-threads technique. Additionally, it is shown that the speedup is increased as more CPU cores are occupied and it approaches to a constant when the number of the CPU cores becomes greater than a threshold.
