摘要
对重叠子孔径算法(overlappedsub aperturealgorithm,OSA)的原理进行了分析和研究,结合极坐标格式处理算法(polar formatprocessingalgorithm,PFA),对条带模式SAR回波数据进行成像处理。利用给出的算法,可以对PFA算法处理中残存的误差项进行补偿。计算机仿真和SAR实际数据成像结果验证了此算法的正确性和有效性。
The principle of overlapped sub-aperture algorithm (OSA) is studied, and a method for processing stripmap SAR data is presented by combining OSA with polar-format processing algorithm (PFA). The purpose of OSA algorithm is to reduce the errors ignored by PFA processing. The results of computer simulation and SAR raw data imaging indicate that this method is feasible and effective.
