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。 This paper presents a new transform convolution method for constructing two-dimensional images from reflected signal data. The reflection data is actually the integral of the reflection characteristic coefficient along the arc of the wavefront with a certain radar beamwidth. When observing planets, asteroids between Mars and Jupiter, or even asteroids using ground-based radar stations, the existence of such a wavefront can be considered as long as the Earth’s rotation speed is relatively large compared to the target’s velocity Arc. It is expected that this new algorithm can be used to construct an image for bending the wavefront.
