| Abstract: | A parallel RD algorithm is achieved by the high speed GPU.A highly parallel and real-time method used in synthetic aperture radar(SAR) is proposed.The result of the experiment shows that the method can meet the demand of real-timeness in SAR.Compared to the traditional method,this method can reduce the cost of hardware and shorten the time of software development. |
