基于JPEG2000的雷达卡技术研究

Research of Radar Image Capture and Compression System Based on JPEG2000

介绍了一种应用目前最新静态图像压缩算法JPEG2000实现的雷达卡的方法,首先说明了雷达卡的硬件实现平台;接着重点说明JPEG2000压缩算法,在JPEG2000编码器里详细说明了DC层进和分量变换、离散小波变换、内嵌编码与最佳截断这三大要点,并给出了相应的程序流程图;再说明了JPEG2000算法从PC到DSP的移植与优化;最后给出了雷达图像采集压缩系统的性能测试。

This paper introduces an application of JPEG2000 image code algorithms to achieve radar image capture and compression systems,have explained the hardware realization platform about radar image capture and compression system first,and proceed to concentrate on explaining the JPEG2000 compression algorithm,preprocessing,discrete wavelet transform,embedded block coding with optimal truncation this three big essentials having explained detailed in JPEG2000 coder,have given out corresponding procedure flow chart.Have explained that the JPEG2000 algorithm arrives at DSP transplanting and optimization from PC again.Have given out the performance test of the radar image capture and compression systems finally.
