摘　　要：为验证小型毫米波雷达成像处理算法的有效性,该文分别以小型滑轨和智能小车为运动载体,搭建了小型线性调频连续波(FMCW)毫米波合成孔径雷达(SAR)实验平台,基于距离多普勒算法设计了适用于去调频体制FMCW信号的SAR成像算法,通过布设字母点阵、自行车和金属罐,开展回波采集试验和成像处理,所获得的雷达成像结果与光学照片的吻合性好。该实验平台可帮助SAR开发人员提高效率。In order to verify the effectiveness of the imaging processing algorithm of the small millimeter wave radar, the small frequency modulated continuous wave(FMCW) millimeter wave synthetic aperture radar(SAR)experimental platform is built with small slide ways and smart cars as moving carriers respectively. Based on the range Doppler algorithm, a SAR range Doppler imaging algorithm for FMCW signals of the de-chirped modulation system is designed. By deploying letter dot matrix, bicycle and metal tank, and conducting echo acquisition test and imaging processing, the radar imaging results obtained are in good agreement with the optical photos. The experimental platform can help SAR developers improve efficiency.
