摘　　要：提出了基于最小二乘法准则提取光学综合孔径观测目标的傅里叶信息 ,给出了系统的理论推导过程 与其它传统条纹信息提取方法作了比较 ,指出基于最小二乘法准则提取观测目标信息周期短 ,速度快 ,可提取观测目标的傅里叶幅度和相位 实验仿真表明 。A method extracting optical aperture synthesis observation objective Fourier information based on least squares is proposed. The theory is deduced. Compared with the other traditional methods, extracting interferogram fringes information based on least square requires much less time , and can extract observation objective Fourier modulus and phase together. Finally, a simulation about extracting interferogram fringes information is executed.
