摘要 对星载合成孔径雷达(SAR)数据进行解压缩是利用SAR星载数据的必要前提。分块自适应量化算法(FBAQ)是一种广泛应用于星载SAR数据的压缩编码方式。本文介绍了FBAQ算法的基本原理,并以Envisat ASAR为例构造了相应的解压缩系统,对系统的整体构造、MDSR提取模块和解压缩模块做了详尽的分析,最后对压缩数据做进行成像处理的验证。该系统是Envisat ASAR实时成像处理系统的一部分。 FBAQ(Flexible Block Adaptive Quantization)algorithm is one kind of compression scheme used widely in spaceborne SAR.This paper discusses the compression scheme of Envisat ASAR and constructs the decompressing system.The architecture of the decompressing system,MDSR(Measurement Data Set Record) module and FBAQ decompressing module is discussed in detail.The result of FBAQ decompressing system is given in the end of paper.This system is applied in the Envisat ASAR real-time processor.
