  • 摘要: 近几年来,由于小型无人机的兴起,基于FMCW体制的合成孔径雷达(SAR)由于体积小,重量轻,成本低得到了快速发展。然而,由于传统的脉冲SAR中的停-走假设不再成立,FMCW SAR成像处理与传统的脉冲SAR有着很大的不同,这样使得在FMCW SAR实测数据进行处理和分析时往往缺乏理论支撑。因此,开展FMCW SAR的信号处理研究具有重要的现实意义和军事价值。目前,国内外关于FMCW SAR的研究主要集中在其成像处理方法上,在回波模拟方向研究甚少,特别是对于既包含分布式运动目标又有静止目标下的真实场景下的FMCW SAR回波快速模拟方法更是鲜有涉及。基于此,该文在FMCW SAR平台脉内连续运动的基础上推导了一种适用于动静目标的精确的FMCW SAR 2维频域模型,并基于该模型提出一种高效精确的FMCW SAR动静目标混合场景回波模拟的方法。点目标和场景目标的仿真试验验证了该模拟方法的有效性,效率分析发现该种模拟方法的效率远高于传统的仿真方法。
