For liner-array sensors on spatial platform, based on the analysis of sensor distortion, pixel size zooming, focal length zooming and sensor rotation, a self-calibration model with eight interior calibration parameters is constructed. Based on orientation image interpolation model, and the movement of exterior parameters, a self-calibration bundle block adjustment model is provided, in which the process of model linearization, exterior calibration parameters of orientation images are introduced. Based on SPOT5 simulation data, experiments have been done on the block adjustment model,which proves that the model will simultaneously and precisely calibrate interior self-calibration parameters and orientation image exterior parameters.%针对航天线阵传感器,综合镜头光学畸变影响、像元尺寸与焦距的变化影响以及镜头的旋转作用,构建8标定参数的内方位自检校模型；利用定向片内插模型,描述影像的外方位元素变化；建立自检校光束法区域网平差模型,在对模型进行线性化的过程中,引入待标定的定向片外方位元素；利用SPOT5模拟数据对平差模型进行实验验证,结果表明,平差模型能够联合标定内方位自检校参数与外方位元素,标定结果准确.
