本文分析了双基地合成孔径雷达成像中线性化前向散射算子F$和重建算子F^{*}F$的微局部性质。在我们的模型中，雷达源和探测器沿沿着一条固定距离的直线运动。我们证明了$F$是一个Fourier积分算子，并从$F$的典范关系给出了投影的映射性质，证明了右投影是一个blowdown，左投影是一个fold。然后我们证明了$F^{*}F$是属于类$I^{3，0}$的奇异FIO。
In this article, we analyze the microlocal properties of the linearized forward scattering operator $F$ and the reconstruction operator $F^{*}F$ appearing in bistatic synthetic aperture radar imaging. In our model, the radar source and detector travel along a line a fixed distance apart. We show that $F$ is a Fourier integral operator, and we give the mapping properties of the projections from the canonical relation of $F$, showing that the right projection is a blow-down and the left projection is a fold. We then show that $F^{*}F$ is a singular FIO belonging to the class $I^{3,0}$.
