曲线航迹和非平坦地形下SAR中奇异性的消除
Cancellation of Singularities in SAR for Curved Flight Paths and Non-Flat Topography
摘要：
本文考虑一个已知地形（可能是非平坦地形）的合成孔径雷达（SAR）的数学模型。在这种情况下，我们考虑的问题，恢复地面反射率的波前集，给定的雷达数据沿弯曲的飞行路径。我们表明，如果奇点位于“镜像点”，那么所得到的数据可能是平滑的，实际上，奇点“取消。“在平坦的地形下，这些镜像点总是离散的，但我们表明，在非平坦的地形下，可能有无限个镜像点家族。
英文摘要：
We consider a mathematical model of synthetic aperture radar (SAR) with a known, possibly non-flat, topography. In this context we consider the problem of recovering the wavefront set of the ground reflectivity, given radar data measured along a curved flight path. We show that if singularities are located at "mirror points," then the resulting data may be smooth; in effect, the singularities "cancel." With a flat topography, these mirror points are always discrete, but we show that in a non-flat topography there may be infinite families of mirror points.
