  • Methods for compressing and decompressing raw digital SAR data and devices for executing them
    Patent number: 5661477
    Abstract: In a method for compressing raw digital SAR data input data are first coded with fewer bits by means of an adaptive block quantization (BAQ) and subsequently vectors are formed from the block-quantized data. The vectors are coded by a special mapping table in order to achieve an effective data reduction. In a method for decompressing digital data, vectors are generated from the coded data by means of a code book table, from which scalar values are formed. After de-standardization of the scalar values, decoded data are obtained in that the scalar values are multiplied for the de-standardization by the standard deviation of each block already calculated during coding.
