最后，以一次地震为例，给出了孔径随震中距、方位角、频率变化的三维图象。

At last, taking one earthquake as an example, this paper gives three dimension patterns of radius of the field with epicenter distance and azimuth as well as frequency.

它可以成功恢复截止频率以外的信息，增加图象细节，从而提高图象分辨率。

It can successfully recover the information out of the cut-off frequency so that we can get more details of an image and enhance image resolution.
