Compression of SAR Raw Data by Block Adaptive Spherical Vector Quantization
Daiyin Zhu · Acta Aeronautica Et Astronautica Sinica · 2006
In this paper,we propose to employ the block adaptive spherical vector quantization for compression of synthetic aperture radar(SAR) raw data.This algorithm exploits the known result that a blockwise normalized SAR raw signal is a Gaussian stationary process.With the comparison and analysis of quality parameters computed on the image,the proposed block adaptive spherical vector quantization shows an interesting performance/complexity trade-off,with respect to other algorithms such as the block adaptive quantization and the block adaptive vector quantization.
