摘要

研究了矢量量化(VQ)码本(和码矢量)大小对合成孔径雷达(SAR)图像质量的影响。利用地形和对比度作为质量度量，将重建的SAR图像与原始SAR图像进行比较。实验表明，图像质量随着编矢量尺寸的增大而单调提高。作者推断，10:1的压缩比在许多应用中是可行的。

The effect of codebook size on the vector quantization of SAR data

The effect of the vector quantization (VQ) codebook (and codevector) size on the quality of synthetic-aperture radar (SAR) images formed from the compressed phase history data are shown. The reconstructed SAR images are compared to the original SAR image using the terrain and contrast ratios as measures of quality. Experiments indicate that image quality improves monotonically with increasing codevector size. The authors infer that compression ratios of 10:1 may be feasible for many applications.<>
