摘要
:Spotlight模式合成孔径雷达成像能用沿上半圆曲线积分的层析成像来实现 .使用解析函数的外推和沿上半圆曲线Radon变换的反演 。
We show that Spotlight mode synthetic aperture radar imaging can be interpreted as a tomographic reconstructing problem along the upper half circular curves. Using the extrapolation of an analytic function and inversion of Radon transform along the upper half circular curves, we obtain the uniqueness theorems of imaging and partial explicit reconstructive formula.
