摘要
距离向多孔径SAR模式是一种高分辨率的宽测绘带成像模式。反解运算和成像处理是距离向多孔径成像算法的两个部分,两者合理配合使用是实现多孑L径模式高精度成像的关键。该文给出了一种采用变尺度傅里叶变换(Scaled F T,scF T,)算法来实现成像处理并与反解运算结合的多孔径成像算法。与已有的处理算法比较,该算法存不显著增加计算钉杂席的条件下可获得较高的成像质量。文巾最后给m了仿真结果。
The SAR working and imaging are the two parts problem for the algorithm mode of range multi-aperture is a high resolution imaging mode for wide swath. Resolving of range multi-aperture imaging algorithm. How to match the two parts together is the key This paper presents a new method based on SCFT (SCaled FT) to solve the problem. Simulation and comparison between different methods is also given to prove the feasibility of range multi-aperture SAR maging method based on SCFT.
