路径差 meaning in Chinese

path difference

Calculations of path - differences in different cases have been analysed . calculations of propagation factor in interference region , diffraction region and transition region has been studied . method of determination of transition region is introduced
研究了多路径和衍射的产生机理,分析了不同地面时路径差的计算方法,分析了地面反射系数的计算方法以及衍射区和过渡区方向图传播因子的计算过程,最后阐述了过渡区的判断方法。
Sar interferometry is an established technique for the estimation of the height location of scatterers , through the phase difference in images acquired from spatially separated locations at either end of a baseline . interferometric synthetic aperture radar ( insar ) can provide accurate digital three - dimensional topographic measurement with all weather conditions day and night
干涉合成孔径雷达( insar )利用合成孔径雷达( sar )系统从空间分离的两个位置对同一区域成像，由相位差与路径差的关系来提取目标的高程信息，能够全天时、全天候的获取大面积、高精度三维地形数据。
