摘　　要：本文设计了FPGA(Field Programmable Gata Array)+TMS320C6678的合成孔径雷达信号处理平台,并在该平台上实现了改进的R-D(Range-Doppler)雷达成像算法的实时处理。并根据雷达成像处理和多核DSP的特点,对算法结构以及并行处理方面进行了优化。经过实验测试,该系统实现了对雷达回波数据的连续实时成像。通过算法改进或两路并联,该平台也可扩展到干涉合成孔径雷达数据处理中或雷达制导系统中。The synthetic aperture radar signal processing platform,which based on the multicore digital signal processor（DSP）TMS320 C6678 and field programmable gate array（FPGA）,is designed. And the imporoved radar real-time imaging algorithm is implemented on this platform. According to the characters of DSP and radar imaging,the algorithm will be optimized further on structure and parallel processing. Experimental results show that the system achieved continuous real-time imaging of radar echoes. But also through parallel or improved algorithm,the system can also be applied to interferometric synthetic aperture radar signal processing or radar guidance system.
