This paper discusses the principles of quasi-real time coding compression of SAR images and the realizing method in the project.According to the information theory and featu res of SAR images
three design methods of coding compression are given. The best one has beenchosen
which uses a digital signal processor
hardwares and softwares
The practice showsthat a 2048?2048 SAR image can be coded and compressed within 80 second by thismethod
the compressing ratio is greater than 10
SNR is greater than 35 db meeting the requirements of the project.
