摘　　要：根据弹载SAR/InSAR成像处理的特点,提出了适合弹载SAR的R-D成像算法,本文分析了近似成像对干涉处理的影响,设计了基于TI最新的TMS320C6678多核DSP和FPGA的硬件实施方案。并通过仿真数据验证了SAR/InSAR实时成像处理性能。Considering the features of SAR/InSAR imaging processing on missile-borne, the Range-Doppler algorithm which is suitable for missile-- borne imaging processing are proposed and simulated, but the effect of approximate imaging on the single pass intefferometric processing is also analyzed, And a hardware implementation solution is designed based on the TI＇s latest multicore digital signal processor and field programmable gate array. Finally, the real-time imaging processing performance is validated with the simulated data.
