摘    要:该文提出一种对机载干涉合成孔径雷达(InSAR)基线的动态测量方法。通过在机载InSAR天线上布设一定数量的控制点,采用单台内方位元素精确标定的数码相机对天线进行实时监测。基于实时控制点图像所建立的共线方程和后方交会算法,解算出相机测量坐标系与控制点辅助坐标系之间的转换参数。将转换参数代入待测点坐标方程后,计算得到天线中心在测量坐标系下的实时三维坐标。在实验室进行的静态和动态模拟实验取得较好结果,验证了该文提出的InSAR基线动态测量方案的可行性。

关 键 词:机载InSAR基线  动态测量  计算机视觉测量  后方交会

Abstract:The dynamic measurement scheme based on single camera for the airborne InSAR baseline is described in this paper. In the above measurement scheme, the calibrated camera is mainly responsible for taking pictures on the pre-designed legends on the antennas of the InSAR system at a reasonable frequency. The 3D coordinates of the antenna phase centers are calculated by the collinear equations and backward intersection algorithm. The scheme is verified feasible by the static and dynamic tests.
Keywords:InSAR baseline  Dynamic measurement scheme  Computer aided vision measurement  Backward intersection
