Hong Wen · Jisuanji fangzhen · 2008
To enhance the computational efficiency of SAR (Synthetic Aperture Radar) echo data simulation for distributed targets, the grid computing technologies were firstly introduced into the domain. The FTP (File Transfer Protocol), TCP/IP(Transfer Control Protocol/Internet Protocol) were used to construct the service of network communication engine, the static and dynamic task scheduling algorithms were used to construct the grid resource scheduling module, the OOP(object oriented programming) , multithreading and other technologies were selected to construct the grid resource surveillance module, grid resource management module, echo calculation module, simulation control module and so on. The SAR echo simulation grid was realized by all the above modules, and the simulation task could be done by many grids’ cooperative work. Experiment results show that the grid has the characteristics of high computational efficiency, easy construction, easy accessing, low-cost and unrestricted geographical position.
