Data Compression of Synthetic Aperture Radar Using Polar Quantizers

Synthetic aperture radar (SAR) produces high bit flow and large amount of data.The compression of data will benefit both data communication and data storage.In this paper,the polar quantization methods are used for SAR raw data compression,the polar quantization methods are introduced,the block adaptive quantization is combined with the polar quantization.At last,the figures of polar quantizers are tested by X-SAR raw data and compared with the quadratic quatizer.
