2) range focusing
距离聚焦
1.
Range focusing is imposed to SAR raw data,which makes it have comparative high relativity,then a vector linear prediction is performed along the azimuth direction,and block adaptive quantization is used to the prediction error series.
该文提出一种新算法,先对SAR原始数据作距离聚焦处理,使其在方位向具有较强的相关性,再沿方位向作矢量线性预测,并对预测残差序列作分块自适应量化。
