摘要

本文提出了一个从反射信号数据构造二维图像的新的变换卷积方法。反射数据实际上是反射特征系数沿着具有一定雷达波束宽度的波阵面圆弧的积分。在利用地面雷达站观察行星

火星与木星间的小游星

甚至是观察慧星时

只要地球自转速度与目标物的运动速度相比相对较大时

就可以认为存在这样的波阵面圆弧。预计可以利用这个新的算法

对于弯曲波阵面的情况构造出图像。

Abstract

A new transform convolution is developed to reconstruct the 2-D picture from projection data. Projection data is obtained from an integration of the reflectivity coefficients of the objects along the circular arc of the wavefront with a radar beamwidth. Such a circular arc is encountered when ground-based radar is used to observe planets

asteroids

or even comets if the Earth’s rotational velocity is large compared to the gross movement of the target. It is expected that the new algorithm can be used to reconstruct images for the curvature of the wavefront.
