Design and Implementation of High Speed and Real-Time SAR Signal Processing Module Based on TMS320C6678

In order to meet the requirements of high speed and real-time in SAR processing system, as well as breaking the bondage that traditional processing board is subject to the algorithm. This paper designs a generic mass storage real-time signal processing module with TI's latest multi-core DSP-TMS320C6678 based on OpenVPX high-speed serial bus standard. This module has standardized, modularized, reconfigurable characteristics. This paper discusses the design of this module and the implementation of typical parallel SAR imaging algorithm mapping on this module. This peocessing module has been applied in a variety of airborne SAR radar signal processing systems and fully validated its powerful processing ability and versatility.
