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.
