摘要
合成孔径雷达(SAR)成像的实时性能与采用的成像算法密切相关,文中对时域相关卷积和频域相乘这两种典型的SAR成像算法进行仿真比较研究,得到频域相乘SAR成像算法在运行时间上比时域相关卷积更具优势,对像素大小为8711240的图像的成像仿真表明前者所耗时间约是后者的10%。
The real-time performance imaging algorithm used. The paper presents of Synthetic Aperture Radar (SAR) imaging is closely related with the comparing study on two kinds of SAR imaging algorithm in simulation, which are convoluting in time domain and spectrum multipling in frequence domain. Simulation results show that the spectrum muhipling algorithm are ten times faster than the other one for a8711240 picture.
