中文摘要：

采用区域网平差的方法进行合成孔径雷达干涉测量（interferometric synthetic aperture radar，InSAR）干涉参数定标，是减小大区域、多个干涉像对重叠处反演高程差异的有效方法。为了提高InSAR区域网平差的答解效能，设计一种利用史赖伯规则的机载InSAR区域网平差干涉参数定标方法。该方法利用史赖伯规则，由连接点误差方程式构建等效误差方程式，可有效减小法方程系数矩阵大小，降低对计算机配置的要求，提高平差的答解效能。采用我国机载双天线InSAR数据进行干涉参数定标试验，改化前后两种方案，干涉参数定标结果没有明显变化，改化后的平差耗时均值减小了，验证了利用史赖伯规则的机载InSAR区域网平差干涉参数定标的正确性和有效性。

英文摘要：

Calibration of inter~erometric parameters with block adjustment ~s a lea~,o ： .--- the difference between heights derived from multiple interferometric pairs over large areas. To im- prove the computational efficiency of block adjustment, a new calibration method for interferometric parameters with airborne InSAR data with block adjustment based on Schreiber rule is proposed. The equivalent error equations are obtained based on Schreiber rule to effectively decrease the dimensions of the coefficient matrix in the normal equations, reduce the requirements for computer configuration,and significantly improve computational efficiency. The calibration experiments are done with Chinese dual antenna airborne InSAR data with different methods. There were few differences in the calibrated interferometric parameters, but the average time of block adjustment decreased. The results show that the proposed method is accurate and effective for calibration of interferometric parameters.
