%X According to the characteristics of noise in SAR,the ridgelet theory,which has been hot research field for its superiority in line feature,was introduced to SAR image compressing.After analyzing the traditional method based on wavelet in detail,a new ridgelet-based compressing approach was proposed.Finally,experimental results demonstrate its good performance,especially for urban SAR image.
