During the research of a representative type of bistatic SAR imaging theory,the error formula of azimuth resolution was deduced to express the effect of differences between Doppler frequency and azimuth frequency,the error formula was extended to monostatic SAR.
针对一种典型结构双基地SAR的多普勒频率与方位频率的差异对精细成像分辨率的影响,推导了分辨率误差公式并推广到单基地模式,通过仿真发现:以往在合成孔径成像中以成像单元的多普勒频率代替方位频率,对成像的方位分辨率造成的误差一般小于4%;但是,在波长变长、斜视角增大和发射信号调频率增大等参数条件下若忽略两种频率的差异有可能引起高达10%甚至27%以上的方位分辨率误差。
