摘　　要：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。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 simu- lation 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 pa- rameters.
