摘要
提出一种基于霍夫曼编码的SAR浮点图像数据压缩方法．通过对DCT系数的研究分析,确定了符合SAR数据特征的量化和编码方法,实验表明压缩效果非常明显．
A float data compression method, based on Huffman coding and for SAR images, is proposed. By the analysis of DCT coefficients, the quantization and coding method suited to the characters of SAR is determined. Experiment shows its obvious effect on compression of SAR images.
