Compression of SAR Raw Data by Transform Domain Coding Techniques
Daiyin Zhu · Telecommunication Engineering · 2006
The block adaptive quantization(BAQ) for compressing the synthetic aperture radar(SAR) raw data is analysed.Then transform domain algorithms based on BAQ,the fast Fourier transform block adaptive quantization(FFT-BAQ) and the wavelet transform block adaptive quantization(WTBAQ),are investigated in detail.With the comparison of quality parameters computed on the image,the FFT-BAQ and WT-BAQ show an increased performance in the compression method with respect to the BAQ.
