Discussion of the introduction of on-board SAR data processing to spaceborne SAR instruments
Martin Süess, C. Schaefer, Rudolf Zahn · 2000
For spaceborne SAR instruments the transmission of the data to the ground is the bottleneck in general. This constraint can be reduced by compression of the SAR data. The different levels of data compression form the conventional block adaptive quantizer (BAQ) to the on-board information extraction, are discussed. It is shown that very attractive compression ratios, optimized to the user requirements, can be obtained if more effort is put in the data processing on board.
