英文摘要	Based on the characteristic and requirement Of aerial remote sensing system, the schemes of whole, software and hardware design of compression system is Put forward. This paper brings forward the high compression performance algorithm, modified CDF97(MCDF97) lifting scheme combined with set partitioning in hierarchical trees (SPIHT) coding, and realizes it in the Visual C++ environment. On this basis, SPM176430ER1000 coprocessor of RTD corporation is adopted as hardware platform. The program is transplanted, debugged and optimized in the code composer studio (CCS) environment, then burned into FLASH of corporation. In the flying experiment, aerial remote sensing data compression system performed well. At 5:1 compression ratio (CR), the average compression speed of every image is 30 to 50 ms, while average decompression speed is 60 ms. Decompression images are displayed in real time in the process of flying, which proved the correction and robustness of the compression system.; Engineering, Electrical & Electronic; EI; CPCI-S(ISTP); 0
