矩阵转置是SAR成像处理中的重要运算,SAR成像的实时巨量数据处理对基于片外存储的矩阵转置算法效率提出了很高的要求,而目前的实时转置算法实现的效率都偏低。文中通过分析片外存储特性,研究和提出适用于SAR 实时成像的矩阵转置算法,占有片内资源少,读写平衡且效率高,配置灵活可组合成较复杂的矩阵转置形式,目前已成功应用于多种模式的SAR成像处理。

Matrix transpose is very important in SAR image processing. Algorithm efficiency of matrix trnaspose based on chip-off memory must be enough to satisfy the process need of mass data,but now implememtation of real-time transpose is not very efficient. Through the feature analyse of chip-off memory, a real-time algorithm to implement matrix trnaspose is presented in this paper. It utilize a few of chip-in memory resource,and achieve to high efficient constant speed within read-and-Write of matrix trnaspose. Now,the method is sucessfully applied in SAR real-time imaging system.
