摘要
基于“NTN”校准理论,分析了“NTN”校准法中的相位卷绕问题及其带来的误差.提出了适用于“NTN”校准法的相位解卷绕技术,给出了使用相位解卷绕技术的“NTN”校准法的计算机仿真结果.
In this article, based on 'NTN' calibration technology, the problem of phase-wrapping encountered in 'NTN' calibration procedure is analyzed. The errors, introduced by phase-wrapping are also presented. The phase-unwrapping technology, applied to 'NTN' calibration procedure is developed, and simulation results of 'NTN' calibration procedure using phase-unwrapping technology are given.
