An Improved BAVQ Algorithm for SAR Raw Data Compression
Falin Liu · Modern Radar · 2007
In this paper,an improved BAVQ algorithm in SAR raw data compression is proposed.First,to reduce the data dynamic range,block adaptive quantization of raw data is implemented and the sign bit of raw data is coded separately.And then,VQ is applied in the data.The result of experiments shows that the complexity of VQ has been greatly reduced.
