摘要

在假设几何形状为矩形且目标固定的条件下，波域SAR聚焦可以精确地实现Stolt插值的hp方法。然而，当必须考虑目标的运动，或者当传感器的轨迹不是与源平行的直线时，Stolt插值只是一个近似。本文首先介绍了均匀目标运动的精确聚焦技术。其次，将Stolt插值扩展到传感器的非直线运动。

SAR Focusing In Non-standard Geometries: A Generalized Approach

Wave domain SAR focusing can he exactly implemented hp means of the Stolt interpolation if rectangular geometries are assumed and targets are fixed. However, when target’s motion has to he considered, or when the sensor trajectory is not a straight line parallel to the sources, the Stolt interpolation is just an approximation. This paper introduces first an exact focusing technique for uniform target motion. Secondly, the Stolt interpolation is extended to non rectilinear motion of the sensors.
