The Real-time Imaging Processing Design Of Missile-borne SAR Based On TI DSP C6678

SAR (SAR) is an important stage in the history of the development of radar,which is widely used in airborne and spaceborne platform. Missile-borne SAR hasbecome a hot of the research in military industrial area, which has added new vitalityfor the development of complex guidance technology.This thesis discusses the real-time imaging technology of Missile-borne SARbased on TI DSP C6678. According to the feature that missile-borne SAR signalcontains large amounts of data and complex signal processing, the signal processingboard is designed based on FPGA+multi-DSP architecture, which has ahigh-performance signal processing capability. The switching CMOS chip joins in thesignal processing board, not only completes the data communication between FPGAand DSP,but also solves the data communication between multi-DSP，demonstratingthe DSP powerful data processing capabilities as well as its interface to a wide range ofpracticality. This paper has a detailed description for TI DSPC6678and the entiremissile-borne SAR real-time imaging processing design, and discusses TI DSPC6678multi-core programming and EDMA3data transmission, simultaneously details theentire missile-borne SAR real-time imaging algorithm procedure, imaging algorithmsimplemented in software and the design of the entire real-time image processingprogram, and finally shows the debugging results of missile-borne SAR real-timeimaging processing. By processing the echo data, it not only meets the requirements ofreal-time processing, but also has a high accuracy.
