介绍利用中国余数定理求解同余方程组的基本公式,并将中国余数定理引入到双基线InSAR相位解缠中。构造关于干涉相位模糊数的同余方程组,设计基于中国余数定理的双基线InSAR相位解缠方法,扩展相位解缠的非模糊区间,为解决干涉相位欠采样区域的相位解缠难题奠定基础。利用不同地区的多套DEM仿真的双基线InSAR干涉图进行相位解缠试验,验证该方法在干涉相位欠采样等区域的解缠能力。 更多还原

【Abstract】 The basic formulation of solving congruence equations with Chinese Remainder Theorem(CRT) is introduced,and CRT is applied to phase unwrapping for dual-baseline InSAR.The congruence equations refer to interferometric phase fuzzy numbers are designed,and the phase unwrapping method for dual-baseline InSAR based on Chinese Remainder Theorem is proposed.In this algorithm,the un-fuzzy phase interval of phase unwrapping is extended,which helps to solve the difficult problem of phase unwrapping in sub... 更多还原
