摘要：
This paper presents the design of one real-time imaging system in airborne C-band Synthetic Aperture Radar. The real-time imaging algorithm based on subaperture-division is described in detail. In order to meet real-time signal. processing the signal processing board with 8 ADSP-TS201S digital signal processors and 2GB SDRAM is designed. This system has excellent real-time processing ability and tremendous data throughput and high expansibility. Finally the raw data of other airborne SAR is used in our real-time imaging system. The image is shown and the processing time is estimated. The results validate the feasibility of our system.
