SARbackprojectionDr**凉兮 上传8.08 KB 文件格式 zip SAR (synthetic aperture radar) is a remote sensing technique that uses radar to create high-resolution images of the earth's surface. The BackProjection algorithm is a commonly used method to generate SAR images. It works by processing the ...
在圆迹SAR成像模型中,一般采用后向投影算法(Back Projection Algorithm,BPA)实现。本文采用C++语言建立了圆迹SAR的回波模型,然后采用BP算法仿真出了点目标。(运行该程序需要配置opencv,对opencv的配置可参考http://blog./destiny0321/article/details/54138434中的部分内容)...

In this paper, we first give the tomographic SAR signal model and describe the TomoSAR processing algorithm under different ...
3.常用的sar成像算法主要包括后向投影算法(back projection algorithm,bpa)、距离多普勒算法(range doppler algorithm,rda)、距离徙动算法(range migration algorithm,rma)等。其中,bpa是一种精确的时域成像算法,但其计算量巨大,不能满足实时成像的要求。rda和rma都是频域处理算法,与bpa相比,它们的计算复杂度大大降低了...
