A Promotion SAR Raw Data Compressing Algorithm Based on BAQ

BAQ algorithm is widely used in SAR raw data compressing, but SAR raw data does not perfectly submit to normal distribution in some cases. One of situation is fractional saturation of raw data. This paper proposes a promoted BAQ algorithm to compress SAR raw data by changing the quantization algorithm. The promoted algorithm increase the SNR of rebuild data with little bandwidth burden.
