%X In the designation of the real-time imaging machine of Mini SAR,the radar return signal is sampled in the intermediate frequency,then Digital Down Converter(DDC) is used to realize quadrature demodulate,which can reduce system complexity and improve radar's performance.The difficulty in the design of the DDC of Mini SAR is firstly given in this paper,i.e.the sampling frequency is as high as 2Gsps and the bandwidth is 900MHz,which leads large difficulty in real-time processing.The optimal architecture of DDC...
