1) near-to-far-field transformation
近场-远场变换
1.
In the paper,the three-dimensional standard parabolic equation(SPE) and near-to-far-field transformation are deduced,and the radar cross section(RCS) of a perfectly conducting sphere is calculated.
文章推导了三维标准的抛物线方程及相应的近场-远场变换理论,并计算了理想导体球的雷达散射截面;数值结果表明抛物线方程算法的引入,在保证一定精度的前提下,大大提高了计算效率,节约了内存。
2) near zone to far zone transformation
近远场变换
1.
In this paper, it is the first time that this method is applied to the calculation of time-domain near zone to far zone transformation.

3) Near-field to far-field transformation
近-远场变换
4) near-field to near/far-field translation
近场到近/远场变换
5) TD-NFFF transformation
时域近远场变换
6) FD-NFFF transformation
频域近远场变换
补充资料:日近长安远
1.南朝宋刘义庆《世说新语.夙惠》:"晋明帝数岁,坐元帝膝上。有人从长安来……因问明帝:'汝意谓长安何如日远?'答曰:'日远。不闻人从日边来,居然可知。'元帝异之。明日,集群臣宴会,告以此意。更重问之,乃答曰:'日近。'元帝失色,曰:'尔何故异昨日之言邪?'答曰:'举目见日,不见长安。'"后以"日近长安远"喻指向往帝京而不得至。
