| Abstract: | Based on the introduction to the development of real_time processing system for remote_sensing images quickly, this paper analyzes some basic tactics, technology and relative hardware platform of parallel processing. It presents a real_time parallel processing scheme for remote_sensing images based on two DSPs concern with the applied background. At the same time, it also gives a processed output of WEN by the above system. It is concluded that this parallel processing scheme will benefit a huge number of real_time data processing technology in_orbit in the future. |
