摘要
干涉合成孔径雷达(INSAR)技术利用两副雷达天线接收同一地面回波的相位差获得实时的高精度数字高程图,可应用于导弹平飞段和俯冲段的地形匹配制导。文中研究了干涉合成孔径雷达技术中的关键处理步骤和方法。利用INSAR获得的高程图进行匹配制导是一种全新的且非常重要的制导方式,适应未来复杂战场环境下的信息化战争。
SAR Interference for realtime digital elevation map is concerned with extracting the phase difference between the same scene of two physical radar antennas.It can be used to flat flight mode and diving mode for terrain contour matching guidance of missile.Key processing steps and methods are discussed in the SAR interference technology.The new guidance of terrain matching profited from INSAR technique is a new and very important guidance mode,which is adapted to information warfare of the complicated war field environment in the future.
