中文摘要：
针对弹载调频连续波合成孔径雷达FMCW SAR俯冲聚束成像的特点,通过构造全时间距离走动校正函数,完成了距离走动校正;采用谱分析的方法进行方位多普勒解模糊处理,消除方位向频谱混叠;在方位向处理中,提出一种改进的非线性调频变标算法,补偿方位空变相位误差,实现了方位向的精确聚焦.点目标仿真实验验证了理论分析与所提成像方法的有效性.
英文摘要：
According to the character of diving‐spotlight imaging for missile‐borne FMCW SAR （fre‐quency modulated continuous wave synthetic aperture radar） ,the range walk iwas corrected by the construction of all time range walk correction function .The SPECtral analysis （SPECAN） was in‐duced to remove the azimuth spectral folding .In the azimuth processing ,an extended nonlinear chirp scaling （ENCS） algorithm was proposed .The azimuth‐variance phase error was compensated ,and a high precise azimuth imaging was achieved .Finally ,some imaging simulations of point targets were given for validating the theoretical derivation and the effectiveness of the proposed imaging method .
