基于GPU加速的合成孔径雷达后向投影成像方法研究
Research on Backward Projection Imaging Method of Synthetic Aperture Radar Based on GPU Acceleration
摘要
Abstract
SAR imaging needs to use algorithms to coherently focus the original echo data to obtain a two-dimensional radar image of the target area.The backward projection algorithm adopts point-by-point coherent focusing in time domain.The algorithm is simple to implement and suitable for any imaging trajectory,so it is widely used.However,this algorithm is extremely time-con-suming and is only suitable for situations where the amount of data is not large or the real-time requirements are not high.In this pa-per,a GPU-accelerated synthetic aperture radar back-projection imaging method is proposed,which solves the problems of low pro-cessing efficiency and difficulty in real-time imaging of traditional back-projection algorithms.关键词
