  • The advantages of wavelet transform constructed with lifting scheme are introduced and compression algorithm based on lifting wavelet for SAR raw data is proposed. Compression performance of the algorithm is analyzed with simulation and real raw data and compared with other techniques by different quality parameters, which show that the algorithm is suitable for compression of SAR raw data.
